1K PT Temperature Sensors
The 1K Platinum temperature sensors for building automation, agricultural and light industrial duty applications.
Air Quality, Hum & Temp
The Node style sensor is a small form factor sensor designed for environment monitoring and control in commercial and institutional buildings. The product supports both Modbus and Bacnet on the RS485port for direct digital readings over the network on all models.
Bacnet Room Setpoint & Temp Display
Bacnet Room Setpoint & Temp Display can be used in environment monitoring and controlling in industrial,commercial and other buildings,Modbus RS485/Bacnet MS/TP for direct digital reading on all models.
Boiler stack temperature sensor and thermowell, 1k Pt
The Boiler stack temperature sensor and thermowell are designed to monitor the temperature of boiler stacks, steam lines and other applications where the temperature is above the operating range of typical HVAC thermistor type sensors. Maximum operating temperature of 300 Deg C (570 DegF).
Electromagnetic flowmeter
The EFM Series is the most economical flanged electromagnetic flowmeter on the market. It is used in 3 to 12” pipe in HVAC, municipal or industrial water, wastewater, pump stations and packaged plant applications. The EFM has no moving parts …
Humidity and Temp Transmitters
Humidity & Temp transmitters are designed for environmental monitoring and controlling in industrial, commercial and other buildings.
Overmolded temp sensor
The Overmolded temp sensor is a 10K type2 thermistor sensor with -50~105 DegC cable, 4.5m in length,two black wires with soldered ends connected to the end.
PM2.5/10 Particle Counter
The PM2.5/10 Particle Counter is designed for environmental monitoring in industrial, commercial and institutional buildings,which provides accurate readings of particle counts in two important sizes, 2.5μm and 10μm.
Water Flow Switch
Water Flow Switch, Stainless Steel Paddles, brass fittings, SPDT switch, liquid, water, ethylene glycol solutions.The TF50-P Flow Switch is used to prove flow in liquid lines using water, ethylene glycol solutions, or other liquids compatible with brass and phosphor bronze parts. The SPDT contact switch is activated by the flow of liquid through the pipes. The set point is adjustable.
CO2 Sensor
The CO2 sensor with Humidity & Temp transmitters are designed for environmental monitoring and controlling in industrial, commercial and other buildings. These transmitters can be used for indoor C02, temperature and humidity monitoring. The modbus interface provides easy setup and integration into large systems.Supports Modbus RTU over both the Ethernet port and the RS485 port,supports Bacnet over both the Ethernet port (IP) and the RS485 port (MSTP).
Air Flow Switch
The duct air flow switch provides feedback of air flow in HVAC duct work. It can be connected directly to the control system as a feedback point or can be directly interlocked to prevent operation of heating and cooling equipment when there is no air flow. Stainless steel paddle resists corrosion. Adjustable spring tension screw allows setting the air flow trip point. The paddle can be trimmed down for higher flow applications. The cable enters through the water tight gland, or the gland can be removed and replaced with an EMT or flex connector for wiring with EMT or metal flex.
Occupancy Sensor
This passive infrared detector, with high stability, has adopted advanced technology in signal processing and provides extremely high detection ability and anti-error alarm. The detector will detect movement of human automatically when intruder passes through the detection area, and it will send out alarm signal to alarm host if there is movement.This product is suitable for the safety of residential houses, villas, factories, markets, warehouses, and office buildings.
Pressure Transmitter
Pressure Transmitter is a kind of standard and most popular transmitter applied in air and liquid pressure measuring,since a high sensitivity silicon pressure chip is employed in the sensor.
Current Sensor: Single phase
The CS series Current Sensors are solid state transducers for measuring the current in fans, pumps and other HVAC equipments.
Dual Float Switch
The float switch is a device used to sense the level of water within a tank,and it can actuate a pump,an indicator, an alarm, or other device.
