The submersible pressure transmitter, sometimes also referred to as a level probe, is a specific design of pressure sensor for hydrostatic level measurement in tanks, wells, shafts and bore holes. For this, the submersible pressure transmitter is submerged directly in the liquid to be measured, and positioned as close as possible to the bottom. There, the submersible pressure sensor measures the hydrostatic pressure, which enables a direct conclusion regarding the current level, i.e. the height of the liquid column above it.

The compact temperature controllers from WIKA offer display, control and monitoring of temperatures. The configuration of the sensor input is made via the multi-function input. Resistance thermometers, thermocouples and standard industrial signals, such as 4 ... 20 mA, serve as the input variable of a temperature controller. The monitoring output can be set either as relay (for slow control), as logic level for the control of electronic solid-state relays (for fast control and high current loads) or as a continuous 4 ... 20 mA output.

Temperature switches are used in a variety of industrial and technical processes. If a preset temperature is reached, then the temperature switch opens or closes a corresponding switch contact. Depending on the requirements, mechanical or electronic switches can be used. In addition to electronic temperature switches and bimetal temperature switches, WIKA's wide range also includes air velocity meters and frost protection thermostats.

Temperature transmitters convert the input signal from a wide range of sensors, such as resistance sensors and thermocouples, but in some cases also from potentiometers, into a standardised output signal (e.g. 0 ... 10 V or 4 ... 20 mA). With digital temperature transmitters, the sensor type and the measuring span can be freely configured, along with many further options such as the error signalisation or a measuring location identification.

Thermocouples are temperature sensors that generate a voltage directly dependent on temperature. Compared to resistance thermometers, they are particularly suited for high temperatures up to 1,700 °C. Instrument designs from mineral-insulated sheathed cable are very resistant against extremely high vibration loads (depending on instrument model, sensor element and wetted materials). The accuracy classes 1 and 2 apply for thermocouples in accordance with IEC 60584 as well as the standard and special classes in accordance with ASTM E230.

Wherever the process temperature has to be indicated locally and, at the same time, limit values must be monitored, thermometers with switch contacts find their application. The switch contacts make or break the circuit dependent upon the pointer position of the indicating measuring instrument. If the reading is significantly above or below a set value, they trigger an alarm, hence also the term “alarm contact”. The instruments are also suitable for starting, stopping or switching processes.

Thermowells or protection tubes from WIKA are used with demanding operating conditions both in solid-machined versions from bar stock material and in fabricated versions with tubular design. The variants offered differ mainly in their designs; with flanges, threaded or for welding in. The connection of the protection tubes by flange is universal and is used in many processes. The compact form of the threaded connection saves space and mounting is also very easy. If the process safety and robustness is important, the thermowells can be welded into the process directly. Furthermore, all connections for sanitary applications and also thermowells in Vanstone design are available without weld seams. The selection of materials and the manufacturing of the thermowells or protection tubes in accordance with global standards or to customer specifications ensure optimal protection for the sensor.

When the compression force transducer has a through hole, it is called a ring force transducer (donut load cell) or a force measuring ring. These force transducers are extremely robust and are suitable for the detection of very high (static) forces. Furthermore, they are suitable for many installation situations. The ring geometry is used in force measurement for a wide variety of spatial conditions. The main fields of application are found in spindle presses, in screw force measurement or even in geotechnology. WIKA offers electrical and hydraulic ring force transducers in diameters from 12 millimetres up to 430 millimetres as well as in various installation heights. Discover our portfolio now.

Discharges during switching operations in SF6 gas-filled plant lead, over time, to increased concentrations of toxic and highly corrosive decomposition products. The use of gas analysis instruments is absolutely necessary to monitor the concentration of harmful decomposition products, thus ensuring long-term plant safety. WIKA offers a complete product line for gas analytics with instruments for measuring individual decomposition products, through multi-analysers with pump-back functionality, to high-precision laboratory equipment.

Calibration baths are electronic controllers which automatically, quickly and with the help of a liquid, supply a temperature. Due to the high reliability and exceptional homogeneity in the measuring chamber, calibration baths are particularly suitable as a factory/working standard for the automatic testing and/or calibration of the widest range of temperature probes - independent of diameter. A special micro calibration bath design enables on-site applications.

By using built-in or external standard resistors, resistance thermometry bridges measure resistance ratios with high accuracy, which are indicative of the temperature, among other things. These instruments are not only used in the field of temperature measurement, but − due to their high accuracy − also in electrical laboratories.
