TST487 热电阻温度计

TST487 热电阻温度计

热电阻温度计

The thermometer is mainly used in the chemical industry but also finds its use in other branches. Preferred applications are vessels or pipes where no high process pressures and no extreme temperatures appear. The device is equipped with a directly wired Pt100-sensor with 4-wire installation. A variety of immersion lengths offers flexible application possibilities.

The thermometer is mainly used in the chemical industry and is also suitable for applications in other industries; the most popular application is vessels or pipes without high process pressure and extreme temperatures. Devices with a head-mounted transmitter are ready for immediate use and offer higher measuring accuracy and reliability than directly wired sensors.

 

Benefits

Modular design with a standard terminal head conforming to DIN EN 50446 and customer-specific immersion length for high flexibility

Highly compatible insert, designed in accordance with DIN 43772

Easy selection of the head transmitter: analog output 4 to 20 mA, HART®, PROFIBUS® PA or FF fieldbus
