OverviewThe CS-PT500 differential pressure transmitter is a cable-connected, fully sealed instrument designed to measure differential pressure of liquids and gases in industrial process control, flow measurement, medical equipment, aerodynamic testing and pneumatic systems. It integrates an OEM differential pressure sensing element with separate pressure ports for positive and negative cavities and can be mounted via the pressure ports or using a capillary/leading tube.
Product Features- Diffusion silicon oil-filled sensing element with 316L stainless steel isolation diaphragm
- Stainless steel housing; maximum static pressure up to 20 MPa
- Temperature compensation and aging screening for stable output
- Fully sealed construction with high insulation and stable performance
- Compact footprint for confined installations
- Suitable for differential pressure measurement of liquids and gases
- Optional explosion-proof version available to meet GB3836.4 ExiaII.CT6
