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.
There are two jumper settings for the analog signals: 0 to 10V and 4 to 20ma.
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.
Differential Air Pressure Switch
PSN40-400A differential pressure switch is used for fan status and dirty filter applications. A knob with pressure values on it allows the setpoint to be adjusted visually in the field. The plastic duct probe tubes, flexible silicon tubing and the mounting screws are included with all models.
Pressure Sensor
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 Pressure Monitor is used to measure differential pressure in the range of +/-1″ wc full scale, +/-8″ wc, 0 ~100 PSI,0~250 PSI.It combines precision, high sensitivity silicon sensing capabilities and the latest ASIC technology to substantially reduce offset errors due to changes in temperature, stability to warm up, long term instability and position sensitivity. BACnet MS/TP and Modbus RTU protocols over RS485,with an ethernet port.
