1K PT Temperature Sensors
The 1K Platinum temperature sensors for building automation, agricultural and light industrial duty applications.
Air Flow Sensor
Air flow sensor is applicable to all kinds of building automation, environment monitoring, HVAC systems. It has current,voltage, 485 output signal to select, using 485 serial port out put and Modbus communication protocol. Wiring Diagram Part Number Scheme
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. Also has transducer outputs configurable as either 0-10V or 4-20ma signals.
AirLab, the All-in-one Indoor Air Quality Laboratory
The “Air Lab” all-in-one sensor is a total solution for measuring the indoor air quality and environment. The sensor is used widely in schools, hospitals and office buildings for demand ventilation and general air quality measurement.
There are many sensor elements in the “Air Lab” but the main attraction is the air particle sensor which can measure both the number of air particles and their density in several bin sizes. Supporting sensors include a C02 sensor, temperature, humidity, occupancy sensor, and TVOC sensor…. pretty much all the parameters you could ask for. The AirLab gives you confidence your building occupants are comfortable and breathing clean air.
The sensor integrates well with existing building automation systems or can operate stand alone as a general air quality monitor. Wireless communications over Wifi is supported using Bacnet IP or Modbus TCP protocols. The sensor also supports wired communications over RS485 twisted pair using BACnet MSTP or Modbus RTU protocols.
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 …
High temperature over molded floor heating sensor
The over molded temperature sensor is typically used for in floor heating systems but is useful for many hot water heating applications. The sensor element is a 10K type2 thermistor sensor with 4.5m cable length rated to 105C. The overmolded design means this sensor can withstand a wet environment for extended periods which makes it suitable for agricultural projects as well.
The cable is tough and flexible so its easy to lay flat under flooring or strapped to the heating pipework.
Humidity and Temp Transmitters
Humidity & Temp transmitters are designed for environmental monitoring and controlling in industrial, commercial and other buildings.
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 five important sizes, 0.5μm,1.0μm,2.5μm,4μm and 10μm.
Temperature and Humidity Transducer with Bacnet and Modbus RS485
Duct temperature and humidity sensor / transmitter well suited to all types of building automation and environmental monitoring applications. The transducer can inteface to the automation system either with an analog signals or digitally over the RS485 network using either …
Temperature Transducer with Bacnet and Modbus RS485
Duct mount temperature only transducer, Bacnet/Modbus over RS485, 0-10v 4-20ma output signal
Water Flow Switch
Water Flow Switch, Stainless Steel Paddles, brass fittings, SPDT switch, liquid, water, ethylene glycol solutions.
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
Air Flow Switch, SPDT 8A@250VAC.The duct air flow switches is a kind of heating,cooling and air conditioning equipment,which is used to control and monitor air,non aggressive gases flow in ducts, chambers, etc.
