9.1. Sensor
Solid-state sensor with electrolyte made of stabilized zirconium oxide, which is pre-heated
to a constant temperature of 1000K (727
o C). The warm-up time is approx. 20 minutes,
and an LED on the front plate indicates that the sensor is ready to measure, while a +15
VDC output signal is transmitted through the 8-pole DIN connector.
9.2. Measuring range
The device can be used to measure oxygen in inert gases, argon, nitrogen and formier gas.
Front control switch and/or electrically controlled switch for measuring gas range
