Omega TLC Series [TCL-3M165E] Precision Temperature Calibrators -31 to 329°F (-35 to 165°C)

Micro Bath Function
The use of calibration liquids offer 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.

Dry-Block Function
The optimum thermal coupling from the block to test item is achieved with the correct adaptor 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 adaptor 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.

Black Body Function
A infrared calibration sleeve is used to calibrate IR pyrometers or thermal imaging cameras. The special surface structure and the asymmetrical shapes create a“cavity radiator” with an emission factor of 0.9994, prevent thereflection 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 befitted 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 calibration 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 abuttingface of the sleeve. The sleeve is designed in such a way that the best temperature homogeneity is achieved in the center of theabutting 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.

A temperature calibrator today needs to be versatile and meet a wide range of requirements. It should be an easily portable device to cope with frequently changing operation locations, as in multiple test bays or in production locations. A calibrator should also be equally suitable for stationary use in the measurement lab or in testing and inspection. To meet these demands, these calibrators are lightweight and easy-to-use at each site. Five temperature calibrators are available to cover the range from -35 to 650°C (-31 to 1202°F) and wet or dry calibration requirements.

• Multi-function Calibrator: TCL-3M165E, Dry Bath, Micro Bath, Infrared Blackbody, and Surface Temperature

Why calibrate? Temperature sensors are subject to mechanical, thermal and chemical stresses. This results in a drift the longer the sensors are in use. Only the regular calibration of the sensors provides information on the difference between the actual temperature and the measured temperature and makes the specific drift visible. This data can be critical to maintaining a stabile process operation. OMEGA™ Dry block calibrators and micro bath calibrators are one of the best means to check and calibrate a wide range of temperature measuring instruments and temperature sensors. Mechanical, electro-mechanical or electronic measurement equipment can be checked with ease. These compact and durable calibrators are easy to transport, user friendly and offer all the features required for the specific test.
