  • Page 7: Description Of Equipment

    Hydrogen leak detector Sensistor ISH2000 Operating Manual Description of equipment Sensistor ISH2000 can be purchased in one of three versions. A desktop model (Sensistor ISH2000), a battery operated model (Sensistor ISH2000C), and a panel mount model (Sensistor ISH2000P). Sensistor ISH2000 Sensistor ISH2000 is equipped with a number of powerful functions making it very easy to integrate in a semi or fully automatic test system.

    Hydrogen leak detector Sensistor ISH2000 Operating Manual Sensistor ISH2000C The battery operated model, Sensistor ISH2000C, has all the Sensistor ISH2000 features apart from the APC system. This means that only passive probes (for example Hand Probe P50) can be used. This is due to power management control. The battery, a Li-ion battery at 14.8 V, can not support the current required to operate external probes.

    Hydrogen leak detector Sensistor ISH2000 Operating Manual Sensistor ISH2000P The panel mount model, Sensistor ISH2000P, has identical features of the Sensistor ISH2000. The difference is that the Sensistor ISH2000P can be installed in the operator’s panel or any other flat surface. The instrument operates on an external +24VCD power supply, provided by the customer.

    Hydrogen leak detector Sensistor ISH2000 Operating Manual Pressure shocks might cause strong sounds which can cause impairment of hearing. Check that all relevant legislation and safety standards are complied with before putting Sensistor ISH2000 into service. Hydrogen Tracer Gas for leak detection When pure hydrogen gas is released in air its flammability range spans from 4% to 75% of hydrogen in air.

  • Page 16: Working Principle

    Hydrogen leak detector Sensistor ISH2000 Operating Manual Working principle Gas Sensor Technology The Sensistor ISH2000 leak detector is using an extremely sensitive hydrogen gas sensor based on a metal-oxide-semiconductor field-effect-transistor (MOS-FET). The gas sensitivity appears when hydrogen absorbs into the sensor through a metal alloy (metal hydride) layer.
