HHDR Type Smart Low Differential Pressure Transmitter
Using differential capacitance as detecting principle to constitute low differential pressure capacitance type transmitter, inputting 0-0.06~1.5kPa pressure, outputting 4-20 mA DC analogue signal.
Service medium: liquid, gas and vapour. Overpressure limit: impose 0~6MPa (absolute pressure) pressure on either side of transmitter. Transmitter is not damaged. Flange can withstand 60Mpa of pressure.
HHHP Type Smart High Static Differential Pressure Transmitter
HHHP type (smart) high static pressure differential pressure transmitter can measure differential pressure under operation pressure of 32MPa. 32MPa proof operation pressure and overloading protection ensure the transmitter to get reliable application in hi-static pressure system.
HHGP/DP Smart Diaphragm Seal Differential Pressure/Pressure Transmitter
HHDP (smart) remote pressure transmitter provides a reliable way of measuring medium and preventing damage to the transmitter by incorporating a diaphragms seal.
FEATURES
Transmitters with remote device are suitable for the following operation conditions:
- Mediums with high temperature should be isolated from the transmitter.
- Measured mediums that cause corrosion to sensitive parts of transmitters.
- Suspending liquid or mediums with high viscosity
- Measured mediums that solidify or crystalize due to change of environment or process temperature
