Description
The MPS sensor with the TrueLEL function measures many flammable gases with one element, does not get poisoned, needs no calibration and works with hydrogen. Its service life exceeds 10 years, as for the infrared sensors, and the LLO2 oxygen sensor works for 5 years. A four-wire addressable scheme shortens cable runs. Installation, calibration and maintenance are done through the display without opening the housing. The SPDT relays Alarm 1, Alarm 2 and Fault switch 1 A at 24 V DC, there is a siren output, and HART 7 is optional. The housing of ADC 12 alloy or 316 steel weighs from 1 to 3.5 kg, has two entries M20 or 1/2 inch NPT, and IP65/66 protection. The operating temperature is from −40 to +70 °C per ATEX/IECEx and up to +60 °C per UL, humidity 0–95 % non-condensing. Repeatability is ±2 % of full scale, and zero drift is not more than ±2 % of full scale per year. Explosion protection Ex II 2 D Ex tb IIIC T80 °C Db for zones 21 and 22.
How to choose
The task determines the sensor type. For many flammable gases and hydrogen MPS is used, for oxygen LLO2, for hydrocarbons the infrared sensor, and for toxic gases the electrochemical one. The aluminium alloy housing is lighter, while 316 steel is more resistant in an aggressive environment. In a hazardous zone Xgard Bright is needed, and in a safe area Xsafe Bright is enough. For pure hydrocarbons in zones 1 and 2 there are also IRmax and IR Plus.
