Thermal Dispersion Flow Switch, 316SS and polysulfone, 1/2” NPT process connection, 6’ of cable with cable gland.

The FS-2 Series of Vane Flow Switches offer an economical flow proving solution. Custom set points tailored for the application are enabled by field adjustable vane layers and a setpoint adjustment screw. These switches are ideal for use in “flow or no flow” applications in cold and hot water systems.

The GS-CDD Series are duct carbon dioxide gas detectors. These devices provide precision measurement of CO2 gas. These sensors use a highly accurate and reliable Non-dispersive Infrared (NDIR) sensor combined with state-of-the-art digital linearization and temperature compensated circuitry to monitor duct CO2, levels. The duct CO2 transmitter principal of operation is based on the Venturi effect of the probe that extends into the HVAC duct. Air flowing through the duct is forced into the vent holes on one side of the probe, into the enclosure, over the CO2 sensor and then the air is drawn back out of the enclosure via the vent holes on the opposite side of the probe. Optional temperature sensor and adjustable relay output is also available.

The GS-CDR Series are room carbon dioxide gas detectors. These devices provide precision measurement of CO2 gas. The GS-CDR series uses a highly accurate and reliable Nondispersive Infrared (NDIR) sensor combined with state-of-the-art digital linearization and temperature compensated circuitry in an attractive, low profile enclosure for room applications to monitor room CO2 levels. A linear analog signal output of 4-20 mA, 0-5 or 0-10 Vdc is provided for connection to a building automation system. Optional features such as temperature sensor, setpoint adjustment, manual override and adjustable relay output are available.

The GS-CMB Series are carbon monoxide gas detectors. They use an electrochemical sensor for reliability and accuracy in even the most critical applications. The standard product features a 2-wire loop-powered output. Optionally, the device may be configured with an alarm relay which operates in 3-wire sourcing mode and/or with Modbus communications.

The PS-2LDP is designed with dual remote sensors that enable it to accept high-pressure ranges up to 500 PSI. All models are rated for overload pressure two times (2X) the maximum full scale range, and burst pressure is five times (5X) the maximum full-scale range.

The static-pressure transmitter is designed with a single remote sensor that enables it to accept high pressure in several ranges up to 500 PSI, 35 Bar, or 3500 kPa. All models are rated for overload pressure two times (2X) the maximum full scale range, and burst pressure of five times (5X) the maximum full scale range.

This series of low-pressure transmitters can be used to measure positive, negative or differential pressure in ranges from 1” W.C. to 20” W.C. (250 to 2000 Pa). The piezoresistive sensor is ideal for monitoring the pressure of air or other clean inert gases and is limited only to those media which will not attack polyetherimide, silicon, fluorosilicone, silicone, EPDM, and neoprene seals.

The Series PS-DXW is a differential pressure switch that makes a contact output based on the differential between two pressure sources. Wetted materials of brass and fluoroelastomer are suitable for use with most gases and water based solutions.

The HS-O_2X Series are relative humidity transmitters for outside air. They use a highly accurate and reliable Thermoset-Polymer-based capacitance humidity sensor along with state-of-the-art digital linearization and temperature compensated circuitry in order to monitor humidity levels. A 60-micron HDPE filter protects the sensor from contaminants. Excellent long-term stability and quick response time combined with temperature compensation make the HS-O_2X Series the ideal choice for the HVAC market. Models with RH accuracy of 2%, 3%, or 5% are available.

The HS-D_2X Series are duct humidity transmitters. They use a highly accurate and reliable Thermoset-Polymer-based capacitance humidity sensor, state-of-the-art digital linearization, and temperature compensated circuitry in order to monitor humidity levels. The sensing element is encapsulated in a 228.60 mm (9”) long by 12.7 mm (0.5”) diameter 304 S/S probe. A 60 micron HDPE filter protects against contaminants. Excellent long-term stability and quick response time combined with temperature compensation make the HS-D_2X Transmitter Series the ideal choice for the HVAC market. Models with accuracy of 2%, 3%, or 5% are available.

The HS-RXXXMP Series are stainless steel wall plate relative humidity transmitters. They use a field-proven capacitive type humidity sensor and microprocessor temperature compensation for reliable, accurate measurement of indoor humidity. The wall plate sensor is perfect for locations requiring periodic wipe down as it features a 304 stainless steel plate with a neoprene gasket. The sensor is protected by a 100 micron sintered stainless steel filter. The plate sensor is available with either 4-20 mA or 0-5 Vdc or 0-10 Vdc output signal types and the transmitter is located on the back of the plate for ease of installation.

TS-D2X Series all-purpose temperature sensors provide precision temperature sensing for ducts. When combined with a TS-TW series S/S thermowell, they can be used to measure liquid temperature in pipes. The TS-D2X single-point temperature sensor uses a precision sensor encapsulated in a 6.00 mm (0.236”) OD, a 304-series stainless steel probe, and it is available in various lengths. All probes provide excellent heat transfer, fast response and resistance to moisture penetration.

This series is composed of single-point temperature transmitters for outside air that use a precision platinum RTD sensor. All probes are constructed so as to provide excellent heat transfer and fast response, and they are potted so as to resist moisture penetration. A sun and wind shield is integrated into the enclosure.
