Temperature sensor
For the measurement of temperatures on the range from
–40 ... 600 °C and/or –50...550 °C with METRAHit S multimeters,
the following temperature sensors are particularly suited:
TF550 oven sensor and TF220 water-proof sensor
The TF550 sensor is especially suited for service applications for
household appliances, i.e. for measurements in ovens to
+500 °C.
The TF220 sensor enables problem-free temperature measure-
ments in gases and liquids such as water temperature in washing
machines, transmission oil temperature and air temperatures in
freezers and air conditioners.
TS Chipset
Due to its compact size, this temperature sensor is suited for
measurements taken at constricted points, e.g. when the sensor
is glued to a temperature sensitive component. It is delivered in
sets of 10 sensor elements.
RI adapter
The RI adapter is a load resistor, which reduces the input resis-
tance of concurrent measuring instruments from about 10 MΩ to
about 200 kΩ.
The RI adapter is plugged onto a
measuring instrument with the help
of safety sockets, and reduces the
measuring point load resistance to
about 198 kΩ with its integrated
200 kΩ resistor. Thus voltages,
which are generated by high imped-
ance interference (e.g. capacitive
interference) are charged with a rela-
tively low impedance. This causes a
sharp drop in voltage at the measur-
ing point. An interrupted or faulty
cable at the measuring point is thus
rapidly detected.
