Pressure transmitters which have been approved for use with intrinsically safe installations in underground mines.
- DPT200 Pressurised Tank Level Differential Pressure Transmitter - Pressurised tank liquid level differential pressure cell transmitter for process plant storage.
- DPT200 High One Side Overload Differential Pressure Sensor - DP transmitter for measuring pressure difference between two pressure points which can tolerate up a very high overload pressure independently on either the positive or negative side port or both together at the same time.

For underground mines there is a separate approval process to the one for non-mining installations of intrinsically safe pressure transmitters. A major consideration for underground mines is preventing ignition of any firedamp (methane gas) which maybe present in the tunnels, chamber and workface areas. For this reason the intrinsic safety approval for mining designates Methane as the gas group.
