Temperature Transducer Pt100, Cu10 and Resistance

Page 1/4 August 2008

Characteristics Electronic transducer for mounting in panels or machines. This transducer is properly designed for conversion of voltage or ohmic resistance into a direct voltage or current signal. It can be used also for temperature measuring by means of two-wire or three wire thermocouples and thermo resistances. The input signal is converted in a proportional, aligned or not aligned output signal, which is independent of the load. Galvanic isolation between input and output signals. Sensor break protection device. The output signal is compatible for connection of various instruments, such as: analogical or digital indicators, graph records, controllers, analogical digital converters and others.

Additional Information The following items contain tips and cautions to be observed by the user for a good functional performance, as well as the maintenance of the instrument and the safety of the installation.

Example for measuring the transformer temperature:

Cautions Be sure the voltages and currents to be connected to the instrument are compatible. Loosen all connections from the instrument before removing it from the installation. Mounting Instructions Observe the environment temperature range. At the place of installation, values for vibration, dust, dirt and humidity, which must remain between the limits, established by the protection class of the housing and the climatic group, specified in this data sheet, have to be observed. For fastening on flat area use two M4 screws. For mounting on DIN rail, use the snap-in device on the rear of the instrument. The connections can be made with eye or fork type cable shoes Instructions for Use When connections have been made, switch on the power supply and check at the output the functioning of the transducer.
