DT301 Positive and Negative Voltage Intelligent Conversion Controller

The hardware part is composed of a patented micro differential pressure precise measurement sensor and a DT301 intelligent controller that complies with the RS485 bus protocol output of intelligent buildings. The software part is based on MCU embedded algorithms, which realize the preset value setting of gradient differential pressure, data acquisition and alarm of various environmental parameters, display of air exchange rate and monitoring of air supply volume, and provide two-level password protection.

DW103 Micro differential pressure transmitter

DW103 micro differential pressure transmitter adopts a high-precision MEMS silicon piezoresistive sensor as the core design scheme, Dewey patented circuit digital compensation technology, and embedded software algorithm. While maintaining the high accuracy and good linearity of the silicon piezoresistive sensor, it eliminates the problem of sensor zero drift, accurately displays small differential pressures, and outputs 4-20mA standard signals. The guide rail installation structure and ABS engineering plastic shell are sturdy, compact in size, and have the characteristics of high strength, light weight, and easy installation.
