T91.x Analogue Temperature Transmitter

T91.x Analogue Temperature Transmitter

3096

The WIKA T91.x analogue temperature transmitter is matched to the specific requirements of the industry. Depending on the output signal, they are particularly suitable for direct connection to evaluation instruments with voltage or current inputs such as PLC's or AD conversion cards in PCs. The WIKA T91.10, T91.20 and T91.30 analogue temperature transmitter convert the temperature-dependent change in resistance of resistance thermometers or the temperature-dependent voltage change in thermocouples into a 0 … 10 V or 4 … 20 mA output signal. With these standardised signals, the measured temperature values can be transmitted directly and safely. The temperature transmitters of the T91 model series are fixed-range transmitters which are supplied with the necessary measuring ranges in line with the customer's requirements. A later fine adjustment of the zero point and the span can be made with potentiometers once fitted.

SITRANS TF Temperature Transmitter

SITRANS TF Temperature Transmitter

3473

The SIEMENS SITRANS TF temperature transmitter is used where other transmitters can't cope. One main point is its rating of IP67. The SITRANS TF transmitter is made of rugged die-cast aluminium or long-lasting stainless steel. It transforms resistance thermometers, thermocouples, Ohm and mV signals into a load independent DC current corresponding to sensor characteristic or a digital signal according to Fieldbus standard Profibus PA or Foundation Fieldbus. The remote mounted sensor prevents the transmitter from heating up at high temperature; there are no vibrations and oscillations due to long neck tubes and protective pipes with SITRANS TF. For tags with difficult access to you can mount your SITRANS TF remotely at easily accessible places and display the measured value on the freely programmable digital display (with version 4 to 20 mA). You can even use the SITRANS TF in a version without a transmitter as a comfortable field display unit for all 4 to 20 mA signals. All SITRANS TF are available in an intrinsically safe or explosion-proof version.

RLS-3000 Float Switch

RLS-3000 Float Switch

8118

The WIKA RLS-3000 float switch with temperature output combines the measurement of the level and temperature of liquids in a single measuring point. The RLS-3000 float switch is suitable for a multitude of media, for example, oil, water, diesel and refrigerants, due to the stainless steel used. A permanent magnet built into the float triggers, with its magnetic field, the potential-free reed contacts built into the guide tube. The triggering of the reed contacts by the permanent magnet is contact-free and thus free from wear. The switching functions of normally open, normally closed or change-over can be realised for the defined liquid level. The additional temperature output enables the medium temperature to be monitored by means of a preconfigured bimetal temperature switch or a Pt100/Pt1000 resistance signal.

The WIKA RLS-4000 float switch with optional temperature output has been designed for the measurement of level and temperature at hazardous measuring points. The WIKA RLS-4000 float switch is suitable for a multitude of media, for example, oil, water, diesel and refrigerants, thanks to the stainless steel used. A permanent magnet built into the float triggers, with its magnetic field, the potential-free reed contacts built into the guide tube. The triggering of the reed contacts by the permanent magnet is contact-free and thus free from wear. The switching functions of normally open, normally closed or change-over can be realised for the defined liquid level. The optional temperature output enables the medium temperature to be monitored by means of a preconfigured bimetal temperature switch or a Pt100/Pt1000 resistance signal.
