- Choice of 8 to 48 channels for various levels of visibility depending on site requirement
- Available for pressure rating upto 207 bar (3000psi) @ saturated temperature
- Dual power supply with 100% redundancy and power supply failure indication (AC/DC)
- Self diagnostic features to detect open-circuit/short-circuit/ probe contamination/ internal component/ ground failure
- Fully validated trip logic eliminates spurious trip
- Fully configurable multiple SPCO/DPCO relay outputs with energized/de-energized and time delay output options
- Multiple remote display facility
- Opto-isolated dual 4-20mA analogue output
- Digital water level indicator in mm (optional)
- Available for hazardous zone (explosion proof) and super-critical application
- The technology uses resistivity discrimination between steam and water to provide indication
- Detection level is dependent on water purity and boiler operating conditions i.e. temperature and pressure of boiler
- Sensing element is a Probe with an insulated tip inserted in a side-arm Water Column. Voltage is applied to the tip: conduction occurs between the tip and the inside wall of the Column
- Resistance <0.1M Ohm indicates water i.e. Probe is immersed in water. Similarly, resistance >0.1M Ohm indicates steam i.e. Probe is in steam.
- An electronic discrimination circuit is used to discriminate the Probe resistance and generate the display logic accordingly
- A vertical display of multiple Green/Red LEDs provide resolution for the water level indication
