3. DESCRIPTION
This digital communication pressure gauge is a high-precision
intelligent digital remote pressure gauge based on MODBUS protocol
RS485 output.
The digital communication pressure gauge adopts a 4 digit LCD
screen, which can display real-time pressure on the spot. At lhe same
time, the pressure signal is transmitted remotely, and the transmission
distance is better than 1000 meters.
Built-in pressure sensor, powerful function, users can change
pressure uni!, calibrate zero deviation, correct filter constant, etc.
This digital communication pressure gauge adopts SS 304 housing
and connection, waterproof cable outlet, waterproof rating of IP65, and
a wide range of media suitability.
* With RS485 signal output
* Adopt standard MODBUS RTU communication protocol
* Adopt all 304 stainless steel shell, strong and durable
* High precision, lang transmission distance, stable performance
* Compact appearance, diameter 60mm
* Compact appearance, diameter 60mm
*High degree of intelligence, users can sei the address, baud rate,
filter constant, re-check, etc.
