The sensor mounting
Sensor head will be placed on the need measuring temperature point, direct measure the point
temperature, secondary use with a variety of temperature meter.
Sensor is installed in the workpiece position as much as possible, to avoid the installation of
next to the door or near the heating object. The insertion depth accord with actual need. The
installation of sensor maintain a position as vertical as possible, but in the case of flow
measurement must install reverse tilt. If you need fix sensor, the container wall can be opened a
fix larger hole than the sensors installation thread diameter, install the sensor fixed on the
container with the nut attached. When the measured object is non- gas or liquid, the temperature
sensor make some close contact with the measured object, in order to improve response speed
and reduce the transmission error.
If the thermocouple output wire need lengthen, you should use the relative thermocouple
ompensation wire with the same polarity, and then connect with the secondary meter. Sensor wire
or compensation wire should directly connect to the secondary meter connecting terminal, to avoid
the use of ordinary wire, otherwise the error will be. Bending connection as little as possible to extend
the use time, frequent bending sensors must be designed for.
