Pt100 Sensors for Industrial Use   The use of a platinum resistance thermometer probe in industrial and scientific applications will normally result in good, accurate temperature sensing without the need for special cables (unlike thermocouples). To achieve the best possible accuracy and reliability, care is needed with installation of the probe, connections, and choice of the host instrumentation.   Choice of wire-wound or flat film sensing resistor.   The resistance elemen ...
Connecting the thermocouple sensor to instrumentation must be done carefully to optimize accuracy and minimize cost. The resultant temperature measurement is only as accurate as the sensor and its interface.   The thermocouple produces only a small thermo-electric e.m.f (typically 40μV/oC) and it is necessary to eliminate or minimize spurious thermal emf signals and Ohmic effects which would otherwise result in incorrect readings.   The length of cable used between the sensor ...
The Labfacility L300 Pt100 temperature alarm / on-off controller can be used in conjunction with a PC to provide accurate monitoring and alarm or on-off control of up to 8- zones simultaneously. It can also be used as a stand-alone instrument without the need for a PC. The PC software supplied with the instrument allows control, configuration, measurement, logging, charting, alarm & relay configuration and calibration functions via a PC. The in-built self-calibration facility of Pt100 ranges ...
