Standard Sensors

Automated Logic carries wide and growing range of standard sensors for HVAC/R applications.

Automated Logic’s Duct Averaging Temperature Sensors feature closed cell foam to seal the probe insertion hole and absorb vibration. Mounting tabs allow for easy installation directly to the wall of the duct. All units have etched Teflon leadwires and encapsulated sensors to create a watertight package that can perform under real world conditions.

Automated Logic’s Carbon Monoxide Sensor offers enhanced electrochemical sensing with outstanding accuracy at low concentrations. This unit features a ventilated Box and is ideal for parking ramps, equipment rooms and warehouses.

Automated Logic Clamp-On Units are designed to monitor  water temperature in retrofit or filled pipe applications. They fit around the outside of a pipe, greatly reducing installation cost. They measure the water temperature by sensing the surface temperature of the pipe.

Automated Logic’s CO2 Duct Sensors are an accurate and reliable way of incorporating demand controlled ventilation. They measure the CO2 in a range of 0 to 2,000, 0 to 5,000, 0 to 10,000, and 0 to 50,000 ppm with a field selectable output of 0 to 5 or 0 to 10 VDC.

Measuring building pressure and air velocity or volume doesn’t get any easier than with the Automated Logic Compact Low Pressure Sensor. The mounting system allows for 2.75” snaptrack, DIN rail, or surface mounting, and the three outputs and 10 pressure ranges are field selectable by simply turning the rotary switch and pressing the “Next” button. The auto-zeroing process is also very easy — simply turn the rotary switch to zero, push the button for five seconds, turn the rotary switch back to your pressure range and walk away.

The Automated Logic Differential Pressure Switch is ideal for air filter monitoring, static pressure proving, airflow proving, or auxiliary fan actuation. Because of its UL 353 Limit Control Listing, this switch can be used in safety circuits to protect heating appliances, heating systems, processing systems, and HVAC/R systems.

Humidity control is an important aspect of any climate control system. Therefore, humidity sensors must be both accurate and dependable. Automated Logic’s humidity sensors are pre-screened for accuracy, eliminating the need for field calibration. The Duct Units are also extremely dependable, with a watertight enclosure.

Automated Logic’s Duct Temperature Sensors feature medical-grade closed cell foam to seal the probe insertion hole and to absorb vibration. Mounting tabs allow for easy installation directly to the wall of the duct. All Duct Units have etched Teflon leadwires and double encapsulated sensors to create a watertight package that can perform under real world conditions. Duct Units have probe lengths from 2” to 18”.

Automated Logic’s Immersion Temperature Sensors are available in 2”, 4”, and 8” probe lengths. The sensor is potted inside a 1/4” stainless steel probe with thermally conductive epoxy. All Immersion Units have etched Teflon leadwires and double encapsulated sensors to create a watertight package that can withstand high humidity and condensation.

The Automated Logic Low Profile “Button” Sensor is ideal for locationswhere esthetics are as important as the temperature measurement. The inconspicuous wall sensor mounts easily by pushing through a 1/2” hole and secured with a peel off tape strip. The only visible portion is a flush 7/8” dot on the wall.

The Automated Logic Low Profile Pressure Pickup Port is ideal for locations where esthetics are as important as the pressure measurement. The only visible portion is a flush 7/8” dot on the wall. The brass fitting on the back accommodates standard 1/8” to 5/32” I.D. tubing.

Automated Logic’s Outside Air Static Pressure Pickup Port is an easy, economical and attractive way of measuring outdoor static pressure. The pickup port also helps stabilize readings because it significantly reduces the pressure fluctuations caused by wind gusts. Differences in building pressure are caused by the operation of supply fans or exhaust fans and usually measure less than .1 inches of water column (W.C.). A gentle breeze of 10 MPH provides a pressure of .048 inches W.C., while a strong wind of 40 MPH provides .772 inches W.C. A gale of 75 MPH can measure over 2.7 inches. Automated Logic’s pickup port significantly reduces these wind pressures for a stable and accurate reading at the pressure sensor and controller.

Humidity control is an important aspect of any climate control system. Therefore, humidity sensors must be both accurate and dependable. Automated Logic’s humidity sensors are pre-screened for accuracy, eliminating the need for field calibration. The outside air units are also extremely dependable, with a watertight (IP66), UV-resistant polycarbonate enclosure.

The Automatd Logic Refrigerant Leak Detector measures the amount of R404A, R410A, R22, and/or R134A present. The Leak Detector measures leaks and spills; it is not intended for critical ppm measurements. Voltage trip levels for R22, R404A, R410A, or R134 leaks and spills are shown in the table. The sensor is temperature compensated for an accurate and reliable measurement.

Automated Logic’s Remote Sensors feature a .75” long encapsulation shell and etched Teflon leads in lengths of 6”, 18”, 5’, 10’, 15’, 20’, and 25’. Remote Sensors are perfect for tight locations. Additional cable options, lead lengths and probe styles are available.

Automated Logic’s Static Pressure Probe Assembly connects to the Automated Logic’s Zone Pressure Sensor to provide duct static pressure or duct air velocity. The angled total probe faces into the airflow to sense the moving air’s total pressure while the static probe senses static pressure.

Automated Logic Spring-Loaded Strap Sensors are designed to monitor water temperature in retrofit or filled pipe applications. They fit around the outside of a pipe, greatly reducing installation cost. They measure the water temperature by sensing the surface temperature of the pipe.

Automated Logic Thermobuffer Temperature Sensor is used to simulate more closely the refrigerator contents rather than the refrigerator air temperature. The fluid filled chamber allows for slower reaction to abrupt temperature changes, yet still maintains long-term accuracy if the change remains permanent. It eliminates the temperature spikes due to frequent refrigerator or freezer door opening and decreases false alarms.

The Automated Logic Thermostat Protector prevents tampering, physical damage, and unauthorized adjustment of thermostats. The attractive, low-profile design is made of thick, durable polycarbonate and features exceptional airflow, key lock protection, horizontal or vertical mounting, and easy installation with hardware included.

The Voltage Converter is a cost-effective way of converting 24 VAC or VDC to 5, 12, 15, or 24 VDC for use on peripheral devices that require DC voltage. The converter is available with a 350 mA output. The mounting system allows for 2.75” snaptrack, DIN rail or surface mounting.

All Stainless Steel Wall Plates feature 1/4” closed cell, medical-grade foam backing which covers the plate and insulates it from wall temperature. All units also feature etched Tefl on leadwires and double encapsulated sensors to create a watertight package that can perform under real world conditions.

The Automated Logic Water Leak Detector is designed to sense the presence of water and alert a central monitoring system of the potentially destructive situation. Upon water detection, the alarm relays change state, and a local red LED illuminates. The transmitter can be set for latching or non-latching alarm, and normally energized or normally de-energized operation.

Automated Logic wall pressure pickup port comes standard on a brushed stainless steel plate sized to fit a common 2” x 4” electrical box. A foam gasket seals the plate or enclosure to the wall to insure the integrity of the measured space. The Wall Plate can be used for pressure alone or as a combination temperature sensor and pressure pickup port. The brass fitting on the back of all Pickup Ports accommodates standard 1/8” to 5/32” I.D. tubing.
