HHAP Type SMART Absolute Pressure Transmitter 

HHAP type (smart) absolute pressure transmitter, for accurate absolute differential pressure measurement. Service medium: liquid, gas and vapour Overpressure limit: 0~14MPa (absolute pressure), Flange can withstand 60MPa pressure. 

HHDP Type Smart Differential Pressure Transmitter 

Using differential capacitance as detecting principle to constitute capacitance type differential pressure transmitter, inputting pressure is 0~1.2kPa to 0~10MPa, etc. 

Service medium: liquid, gas and vapour. Overpressure limit: impose 0 (absolute pressure) ~6MPa pressure on either side of the transmitter. The transmitter is not damaged. The transmitter’s operation static pressure is detailed in the models and specifications sheet. 

HHDP Type Smart Differential Pressure Transmitter 

Using differential capacitance as detecting principle to constitute capacitance type differential pressure transmitter, inputting pressure is 0~1.2kPa to 0~10MPa, etc. 

Service medium: liquid, gas and vapour. Overpressure limit: impose 0 (absolute pressure) ~6MPa pressure on either side of the transmitter. The transmitter is not damaged. The transmitter’s operation static pressure is detailed in the models and specifications sheet. 

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
