The Clorius Duostats are thermostats, type V, which via two sensing elements in a common hydraulic system act on one and the same control valve. Two basic types are available: Clorius V4.05- or Clorius V4.10 duostat, depending on the preferable proportional band PB, and the valve size. The sensing elements are two spiral sensors for the ventilation duct or two-rod sensors (a combination of one spiral sensor and one-rod sensor may be supplied in certain combinations). The effect, which the two sensing elements have on the adjustment, is proportional to the liquid volume of the individual sensors. Duostats are therefore available with varying proportions between the liquid volumes of the two sensors (sensor proportions) and in that way they can meet the requirements made by a number of different adjustment problems. As the adjustment result is a weighted average value of the temperatures of the two sensors, nofixed adjustment value can be indicated. Hence, Duostats are not equipped with a temperature scale, but with a marking for adjustment towards higher or lower temperatures, respectively.

The SIKA TP18 200E basic temperature calibrator can be used everywhere, including on-site in workshops, test and measurement rooms as well as laboratories. The SIKA TP18200E temperature calibrator covers a broad spectrum of industries with diverse applications. The optimum thermal coupling from the block to test item is achieved with the correct adapter sleeve. Ideally, the internal diameter of the sleeve is 0.5 mm larger than the outer diameter of the test item. With the aid of the adapter sleeve, straight temperature sensors of virtually any length and diameter can be calibrated. The dry block covers the entire temperature range without the need to change the calibration medium. Viscosity, flashpoints or outgassing are of no concern.

The SIKA TP M 255S temperature calibrator can be used everywhere, including on-site in workshops, test and measurement rooms as well as laboratories. The SIKA TP M 255S temperature calibrator covers a broad spectrum of industries with diverse applications. The optimum thermal coupling from the block to test item is achieved with the correct adapter sleeve. Ideally, the internal diameter of the sleeve is 0.5 mm larger than the outer diameter of the test item. With the aid of the adapter sleeve, straight temperature sensors of virtually any length and width can be calibrated. The dry block covers the entire temperature range without the need to change the calibration medium. Viscosity, flash points or outgassing are of no concern. Micro bath function The use of calibration liquids offers certain advantages if temperature sensors with an unusual shape and size are to be tested. The test item is immersed directly into the liquid without an insulating air gap, resulting in direct temperature contact between the calibrator and the test item. The liquid, such as silicone oil, is chosen depending on the calibration temperature required. The continuous adjustment of the magnetic stirrer together with the removable sensor basket agitates the calibration liquid to create a large measuring zone. Furthermore, the sensor basket guarantees unhindered stirring and helps protect the tank floor.

The SIKA TP3M 255E temperature calibrator can be used everywhere, including on site in workshops, test and measurement rooms as well as laboratories.

With the aid of the adapter sleeve, straight temperature sensors of virtually any length and width can be calibrated. The dry block covers the entire temperature range without the need to change the calibration medium. Viscosity, flashpoints or outgassing are of no concern. Black body function A patented infrared calibration sleeve is used to calibrate IR pyrometers or thermal imaging cameras. The special surface structure and the asymmetrical shapes create a žcavity radiatorœ with an emission factor of 0.9994, prevent the reflection of interference radiation and emit the required temperature in an ideal form. The pyrometer is simply held at the specified distance above the measurement opening, thereby forming the desired measurement area on the bottom for the calibration to be performed. A support base can be fitted directly on the unit. Surface temperature function Surface temperature sensors are calibrated using special sleeves that are fitted vertically with the required contact force. Switching the SIKA TP3M 255E temperature calibrator control to the external reference sensor creates the best possible temperature reference point on the surface of the sleeve. The reference sensor is located directly beneath the abutting face of the sleeve. The sleeve is designed in such a way that the best temperature homogeneity is achieved in the centre of the abutting face. The special design of the abutting face enables good thermal contact. There is no need to use a thermally conductive paste or other thermal conduction aids. Micro bath function The use of calibration liquids offers certain advantages if temperature sensors with an unusual shape and size are to be tested. The test item is immersed directly into the liquid without an insulating air gap, resulting in direct temperature contact between the SIKA TP3M 255E temperature calibrator and the test item.

The continuous adjustment of the magnetic stirrer together with the removable sensor basket agitates the calibration liquid to create a large measuring zone.

The temperature controller, which consists of a thermostat and a valve, is used to control the temperature in central heating systems, district heating systems, industrial plants or industrial processes, and marine systems. The Clorius V2 / V4 / V8 Self-Acting Thermostats can be used to control cold or hot water, steam or oil in heating and cooling systems. Thermostat A thermostat consists of a sensor and a capillary tube, fi filled with liquid, and an adjusting cylinder. The thermostat type designations and technical data are specifi ed in fi g. 2. With temperatures above 170ºC, a cooling unit must be fi fitted between the valve and the thermostat – see fi g. 1. The thermostat is self-acting and works on the principle of liquid expansion, it is sturdy in its design, and works with a large closing force – see fi g. 2 Sensor The following sensor types are available : Rod sensor in copper or stainless steel and spiral sensor in copper with threaded connection according to ISO R7/1. Spiral sensor (copper only) with air duct flange. Rod/spiral sensor with steel flange DN 50, PN 40 and DN 50, PN 160. Sensor without connection. Usually used with capillary pack box for temperature control in tanks. Capillary Tube The capillary tube is made of copper, stainless steel, or PVC-coated copper but can also be delivered with flexible iron tube protection.
