Overview
An intrinsically safe pressure transmitter for flammable atmospheres, measuring liquid, gas or steam pressure and transmitting a 4~20 mA signal to a control system or indicator. Used for pressure measurement and control in petrochemical, gas and other hazardous areas.
Features
- Intrinsically safe circuit, Ex ia IIB T6 Ga (refer to the certificate for the exact marking).
- Lightning, RF and EMI protection.
- Shock, overload, vibration and corrosion resistance; digital temperature compensation.
- Stainless steel construction, long-term stability ≤±0.2%FS/year.
