Aerosense DPT-Flow Differential Pressure Transmitter Modal DPT-Flow-7000-D Range 0-7000 Pa

Aerosense DPT-Flow Differential Pressure Transmitter Modal DPT-Flow-7000-D Range 0-7000 Pa


Series DPT-Flow Differential Pressure cum Air Flow Transmitter
 engineered for building automation in the HVAC/R industry.It measures the volume Flow,Velocity, and static and differential pressure.The DPT-Flow Devices can be connected directly to pressure measurement points in the centrifugal fan.It has an optional Auto-Zero Feature which electronically adjusts the Transmitter Zero at predetermined time intervals Every 10 Minutes. The Auto-Zero adjustment takes 4 seconds.The AZ Calibration eliminates all output signal drift due to thermal,electronic, or mechanical effects.

ELECTRICAL CONNECTIONS

 

AZ-Calibration is a Function in the form of an automatic zeroing circuit built into the PCB.The AZ-Calibration electronically adjusts the transmitter zero at predetermined time intervals Every 10 Minutes.The AZ-calibration eliminates all output signal drift due to thermal,electronic or mechanical effects,as well as the need for technicians to remove high and low pressure tubes when performing initial or periodic transmitter zero point calibration The AZ adjustment takes 4 seconds.To avoid conflict with the BAS system,the output and display values will freeze to the latest measured value,after which the device returns to its normal measuring mode.Transmitters equipped with the AZ-calibration are virtually maintenance free
