Surface mounted thermometer Type TP 30 / TW 39 T 238 SPECIAL DESIGN FOR TEMPERATURE MEASUREMENT WITHOUT CONTACTING THE MEDIUM, FOR EX. FOR MOUNTING AT TANK WALLS CONSTRUCTION WITH CABLE OR FIELD-HOUSING IP 67 OPTIONAL WITH PROGRAMMABLE TRANSMITTER 4-20 MA, OPTIONALLY PROFIBUS PA OR HART Description The temperature sensors are specially developed for measurement of tank surface temperatures. The sensor tip is flexible and movable in the range of 4 mm. This enables the maximal contact with the surface and guarantees high accurate measurement of the surface temperatures during stationary processes. In order to attain good measurement results it is important to eliminate environmental effects, as for ex. caused by refrigerating units or changeable outside temperature by external mounting. The use of the welded socket makes mounting fast and easy. Depending on the prevalent mounting possibilities and situations, the device can be either assembled or alternatively directly welded into the tank. lt is recommended to use the heat-conducting paste to improve additionally the temperature exchange. The resistance Thermometers can be delivered with directly connected cable or with stainless steel housing, and can be used due to their protection class IP 67 outdoors. Simple or double temperature sensors Pt 100 according to EN 60751, Class A, guarantee the high accuracy. For transmission of measured values programmable transmitters either with analogue signal or HART or PROFIBUS PA can be installed.
