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. Also has transducer outputs configurable as either 0-10V or 4-20ma signals.
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).
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 …
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.
Duct temperature and humidity sensor / transmitter well suited to all types of building automation and environmental monitoring applications. The transducer offers two options for intefacing to the automation system, either with an analog signal or over the RS485 network …
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.
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).
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.
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.
The 330mv AC series of split core current sensors are ideal for installation on existing electrical wiring by snapping around the conductor without requiring and rewiring or interruption of the existing power cabling. UL listed product.
