Characteristic features
Temperature probe in stainless steel housing
protection tube 6x40 mm for submerged sleeve
PUR connection cable, shielded
Typical areas of application
Heating and solar systems
Building instrumentation
Industrial applications
Application areas
Universal, temperature probe for general use, e.g.
heating and solar systems or for industrial
applications. The protection tube of stainless steel
grade 1.4571 is mechanically robust and suitable
for food grade applications. The material is
resistant against many type of chemicals.
Because of the small outside dimension of 6 mm,
direct mounting in submerged sleeves is possible,
which ensures good thermal contact to the
medium.
This temperature probe, together with Universal
sensor switching module 156503/17/30, results
into a thermostat for universal applications.
Resistance table
The precise NTC probe is suitable for many
applications, in which temperature is to be
measured with high precision. As a closely
tolerated NTC is used as sensor element,
normally it should possible to interchange the
sensor without re-calibration. The resistance value
of the probe is directly dependent on temperature.
The high slope of impedance curve enables a
simple evaluation circuit. With the integrated
parallel resistance, the exponential resistance
curve S-form of NTC is pre-linearised. The curve
has maximum slope in the range of about 20°C.
The following table further gives the relationship of
resistance with respect to temperature. The
tolerance on resistance value is approx. ±2%. You
can get the detailed characteristic with
intermediate values on request.
