SMART Absolute Pressure Transmitter
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.
Smart Standard 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.
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.
Smart High Static Differential Pressure Transmitter
Smart High Static 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.
DP Smart Diaphragm Seal Differential Pressure/Pressure Transmitter
DP Smart Diaphragm Seal Differential Pressure/Pressure Transmitter provides a reliable way of measuring medium and preventing damage to the transmitter by incorporating a diaphragms seal.
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
Inline Pressure Transmitters
Diffusive Silicon Pressure Transmitters
Diffusive Silicon Series pressure transmitters use imported diffusive silicon type and ceramics with high quality as the sensitive measuring components, and employ application-specific integrated modules. Temperature shift compensation, zero and non-linearity compensation ensure accurate measurement and transmission of medium pressure change for liquid, gas and vapour.
