类型: 带TW40装配式护套 法兰式热电阻温度计事防爆 型号: TR10-F 带TW40 测量精度: 2.5(℃) 输出信号: 4-20 品牌: WIKA/威卡 工作电压: 10-30(V) 加工定制: 是 测量范围: -200 ... +600 °C(℃) WIKA TR10-F 带TW40装配式护套 法兰式热电阻温度计防爆 Flanged resistance thermometer Model TR10-F with fabricated thermowell model TW40 Flanged resistance thermometer model TR10-F with fabricated thermowell model TW40 Applications Machine building, plant and vessel construction Energy and power plant technology Chemical and petrochemical industry Food and beverage industry Sanitary, heating and air-conditioning technology Special features Application ranges from -200 ... +600 °C Model TW40 fabricated thermowell included Spring-loaded measuring insert (replaceable) Explosion-protected versions Ex-i, Ex-n and NAMUR NE24 Description Resistance thermometers of this series are designed for fitting into vessels and pipelines. Standard flanges to DIN EN or ASME are available. These temperature probes are suitable for liquid and gaseous media under moderate mechanical load. The model TW40 thermowell is fully-welded and screwed into the connection head. Stainless steel thermowells are suitable for normal chemical conditions. Coating is recommended as an optional extra with chemically aggressive media, or solid wear-resistant coating for abrasive media. The interchangeable measuring insert can be removed without taking out the complete probe from the plant. This enables inspection, verification of the measuring chain and, when servicing is necessary, replacement during operation and while the plant is running. The choice of standard lengths assists with short delivery times and the possibility of stocking spare parts. Insertion length, flange size, thermowell design, connection head and sensor can each be selected to suit the respective application. Optionally we can fit analogue or digital transmitters from the WIKA range into the connection head of the TR10-F. Sensor The sensor is located in the measuring insert. This is replaceable and spring-loaded. Sensor connection method 2-wire The lead resistance is recorded as an error in the measurement. 3-wire With a cable length of approx. 30 m or longer, measuring errors can occur. 4-wire The internal lead resistance of the connecting wires is negligible. Tolerance value of the sensor to DIN EN 60751 Class B Class A Class AA The combinations of a 2-wire connection with Class A / Class AA are not permissible, since the lead resistance of the measuring insert negates the higher sensor accuracy.
