Application
Monitoring of the water level within an underground coal mine.
Key Requirements
- Certified for use within an underground coal mine (potential for methane gas)
- Analogue output to measure up to 30m of water depth
- Facility for cable and catenary connection to lower the transmitter 300m down a bore
- High accuracy and repeatability
- Sensor referenced to atmosphere
Solution
STS ATM.ECO/N/Ex submersible pressure transmitter with the following key features;
- IECEx certification
- 4-20mA output with 3X overpressure on a 0-30m range transducer
- 330m intrinsically safe ‘blue’ cabling with Viton seals and catenary fittings on the rear of the stainless steel housing
- 0.1% FS accuracy with temperature compensation from -5 to 80 deg C
- Sensor referenced to atmosphere via an integrated ‘breathing’ filter
