Description Data
The ST700IR gas detector for combustible gases is Gas Hydrocarbons
assembled in a chrome-plated ABS housing. Weight ~500 g
Material housing Chrome plated ABS
The sensing head is equipped with a replaceable infrared Sensor housing SS 316
sensor. The detector is a fully digital and extreme accurate Power supply 12-35 VDC
measurement device. The output signal is a standardised Power consumption max 100 mA
4-20mA signal. The power supply of the sensing head is Accuracy ±5%
supplied by a three-core screened connection cable. Measuring range 0-100% LEL
The ST700IR features all necessary calibration functions Response time t90 < 20sec.
inside the detector. Hence, the calibration of the detector Signal 4-20mA (3-wire)
can be performed by a single person. This one-man Measuring principle Non Disperse Infra Red
calibration feature offers the highest degree of accuracy Sensor Infrared
and disposes the need for a second calibration on the gas Loop resistance max 250Ω
detection control unit. Sensor lifetime Min. 7 years in air
Temperature range -10°C to +55°C
Protection class IP65 (excl. sensor)
Cable entry Od Ø 10-13 mm
