1K PT Temperature Sensors
The 1K Platinum temperature sensors for building automation, agricultural and light industrial duty applications.
Air Flow Sensor
The Air Flow Sensor senses air flow in HVAC ducts and report air flow over both analog and digital (Modbus an Bacnet) communication protocols. An instrument grade Pitot tube provides outstanding accuracy with maximum efficiency over various duct widths.
Setting analog output range through Modbus register
Air Quality, Hum & Temp
Notice: Temporary price increase of ~$8USD due to the global CPU shortage Accept our apologies, we’re not sure how long this will last but it could be a couple months
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).
Clamp Current Transformer
The Current sensor,output 0-330mv,Current Frequency 45Hz-65Hz
Clip On Temperature Sensor
The sensor is housed in a copper tube with a slightly curved surface to make intimate thermal contact with the pipe. Temperature changes in the pipe fluid are conducted very quickly through the sensor housing to the element inside. The copper pipe strap fits makes for quick installation on either 1/2 inch or 3/4 inch pipes.
The 3 meter long cable is 24 AWG stranded copper wire with a UL2651 rating and is registered under UL file number UL42323. The thermistor is a 10K type 2 temperature curve compatible with most DDC systems on the market
Duct Averaging Temperature Sensors
Temperature is detected by a range of thermistors. The
special mechanical construction the sensor is able to detect
temperature throughout its entire length.
