HR310 Series Digital Pressure Transmitter-HighReach

HR310 Series Digital Pressure Transmitter

HR310 series digital pressure transmitter use top quality pressure components with mixed signal processing technology and unique compensation methods to realize high precision digital pressure measurement, F S digital linearity correction, full temperature digital temperature compensation, compensation data stored in nonvolatile memory, multiple safety protection system to avoid the products cannot be used due to correction data lost; Circuit part with power and watchdog monitor, mechanical part with full seal stainless steel structure, both of them improve the reliability of the whole transmitter. The high precision digital pressure transmitter is widely and successfully used in many industries, such as pressure measurement of industry, hydrology and water conservancy, geological prospecting and etc.

Anti-surge, electromagnetic interference

High stable pressure sensing unit, with long-term stability

High precision, up to 0.05％F.S(Linearity, repeatability, hysteresis)

Adopts mixed signal microprocessor to realize high precision compensation

RS485 Standard MODBUS-RTU Protocol output, can be used in DCS or PLC system;

Low power consumption, when operating at full speed, the power consumption is about 4mA, outstanding performance on external battery supply
