EMPERATURE PROBES
The instrument accepts the input of Platinum temperature probes with resistances of 100 Ω and
1000 Ω .
The Pt100 are connected to 4 wires, the Pt1000 to 2 wires, with the excitation current chosen mini-
mizing the sensor self-heating effects.
The 4-wire and 2-wire probes with direct input are checked for conformity with class A toler-
ance according to norm IEC751 - BS1904 - DIN43760.
The temperature probes are automatically detected by the instrument (please see the description of
the Probe Type menu on page 12).
The °C or °F unit of measurement can be chosen for display, printing, and logging using the °C/°F-
ESC key.
How to measure
The temperature measurement by immersion is carried out by inserting the probe in the liquid for at
least 60mm; the sensor is housed in the end part of the probe.
In the temperature measurement by
penetration the probe tip must be inserted to a depth of at least
60mm, the sensor is housed in the end part of the probe. When measuring the temperature on frozen
blocks it is convenient to use a mechanical tool to bore a cavity in which to insert the tip probe.
In order to perform a correct
contact measurement, the measurement surface must be even and
smooth, and the probe must be perpendicular to the measurement plane.
So as to obtain the correct measurement, the insertion of a drop of oil or heat-conductive
paste is useful (do not use water or solvents). This method also improves the response time.
Instructions to connect the TP47 module for conductivity/temperature combined probes,
4-wire Pt100 probes, and 2-wire Pt1000 probes
All Delta Ohm probes are provided with a connector. The HD2106.1 and HD2106.2 instruments
also work with conductivity/temperature combined probes, direct 4-wire Pt100 probes, 2-wire
Pt1000 probes manufactured by other producers: for the instrument connection is prescribed the
TP47 connector to which the probe's wires should be welded.
The instructions to connect the probe to the module are provided below.
The module is supplied complete with fairlead and gasket for 5mm maximum diameter cables.
