  4. Humidity and occupancy contro
  5. DCV (Demand-Control Ventilation)
  6. Humidity and ventilation control
  7. Occupancy and ventilation control
  8. Humidity, occupancy, and ventilation control

* All units have a temperature sensor (standard)

Temperature

Room Temperature

Stylish, and economical room temperature sensors and transmitters, incorporating a 10,000 ohm (@ 77° F) thermistor for precise, stable temperature sensing. These sensors may be surface mounted on a hollow wall.

Different models for different applications are available and may include setpoint adjust via rotary dial or up/down buttons, override buttons, LCD display or LED status indicator.

Temperature Sensors

STE-1400 Series 10,000 ohm, Type III thermistor, temperature sensors are available in different housings for surface, duct, duct averaging, immersion, strap-on, and outside air applications.

Thermowells

The thermowell is machined from a single piece of brass or stainless steel to provide a rugged and leak proof well for our temperature sensors

Humidity & Temperature

Room Temperature & Humidity

The THE-1102 can be wall-mounted for use with building automation systems in commercial buildings, hospitals, museums, or other facilities requiring accurate measurement of relative humidity and temperature. It transmits separate relative humidity (RH) and temperature signals for use in temperature, humidity, or enthalpy-based control applications.

Duct Temperature & Humidity

The THE-1002 is designed for use in ducts for building automation systems in commercial buildings, hospitals, museums, or other facilities requiring accurate measurement of relative humidity and temperature. It transmits separate relative humidity (RH) and temperature signals for use in temperature, humidity, or enthalpy-based control applications.

Pressure

Air Differential Pressure Switch

Used to remotely sense over pressure, vacuum, and differentials of pressure. with an SPDT switch that allows remote status/alarm indication.

The models have three different pressure ranges to meet nearly any need.

Water Differential Pressure Switch

Differential pressure switch is an effective pressure monitoring solution for liquids and non-aggresive gases.

The unit is designed for both flow proving and flow failure detection to cover the range of 0.3 to 4.5 Bar (4.35 to 65.25 Psi). Approximate setpoint can be viewed on the dial at the front of the unit.

Pressure Sensor

The series of pressure transducers incorporate a gauge pressure transmitter featuring low hysteresis, excellent repeatability, and long-term stability. Up to four field-selectable input ranges are available in most models. The field-selectable feature provides a single model that can be configured to cover all the input pressure ranges for any given application.

Liquid Pressure Differential

The liquid pressure transducers incorporates a wet/wet differential pressure transmitter featuring low hysteresis, excellent repeatability, and long-term stability.
Up to four field-selectable input ranges are available in most models. The field-selectable feature provides a single model that can be configured to cover all the input pressure ranges for any given application

Flow

Air Flow Sensor

The duct airflow transmitter registers the airflow speed which is measured and converted to a 4 – 20mA or a 0 – 10 V signal. Airflow speeds can be measured in the range of 0 – 8 m/s or 0 – 16 m/s.

Detectors

Smoke Detector

The Smoke Duct Detector is the latest innovation for early detection of smoke and products of combustion present in air moving through HVAC ducts in Commercial, Industrial, and Residential applications. The unit is designed to prevent the recirculation or spread of smoke by air handling systems, fans, and blowers.

The duct smoke detector can be selected with an ionization or photoelectric smoke detector with a metal sampling tube.

Carbon Monoxide

The carbon monoxide detector uses a superior electrochemical sensor for reliability and accuracy in even the most critical applications with a range of 0-300 ppm CO. The detector may optionally be configured with an alarm relay which operates in 3-wire sourcing mode and/or with Modbus communications.

Carbon Dioxide

The CO2 monitor uses a highly accurate and reliable Non-dispersive Infrared (NDIR) with state-of-the-art digital linearization and temperature compensated circuitry in an attractive, low profile enclosure for room applications and a duct mount version to detect CO2 levels and provides a linear analog signal output of 4-20 mA, 0-5 or 0-10 Vdc signals.

Available with ranges of 0-2000 ppm (Single beam) or 0-20,000 ppm (Dual beam).

Air Quality Detector

The Air Quality Sensor uses an advanced MEMS metal oxide semiconductor sensor to detect poor air quality. The sensor reacts quickly to detect a broad range of VOCs such as smoke, cooking odors, bio-effluence, outdoor pollutants and from human activities.

Water Detector

The water leak detector is a microchip-based device that uses gold-plated sensing probes to detect the presence of water or other conductive liquid.  The detector is powered by an AC or DC source & features normally open and normally closed (form C) relay contacts.

The detector c/w the specified length of conductivity cable.
