Differential Pressure Transmitter 4-20mA RS-485 Capacitive Pressure
Transducer Sensor Compatible with 316LSS
Description 4-20mA 3051 Type Differential Pressure Transmitter
Digital • Intelligent pressure / differential pressure transmitter
optional HART module, when the transmitter installed HART module,
with HART communication capabilities, can be used to operate the
general operation of the general controller. With our company to
provide special communications equipment and software can be
calibrated and temperature compensation and other operations.
Signal conversion, signal acquisition and processing and current
output control using an integrated design, the structure is more
compact and reliable. Sensitive parts with a stable, reliable,
anti-vibration characteristics.
