Description

The model TG54 bimetal thermometer has been developed and is manufactured in accordance with the EN 13190 standard. The thermometer meets the high requirements of the process industries.

Especially in the chemical and petrochemical, oil and gas, power engineering and shipbuilding industries, the temperature measuring instrument manufactured from stainless steel is used successfully. The robust, hermetically sealed case with IP65 ingress protection enables use with harsh external conditions and high vibration.

For further approvals see page 9

Fig. right: Back mount, adjustable stem and dial

With a count of four different nominal sizes, an optimal matching to the available space and mounting conditions is possible.

At an easily accessible point on the back of the case, the zero point can be easily corrected.

The model TG54 meets the high requirements for resistance against aggressive media. As an option, the case, the stem and the process connection can be made from 316L.

Special features

  • Nominal sizes 63, 80, 100, 160 mm [2.5, 3, 4, 6"]
  • Robust, hermetically sealed case
  • External reset for setting the reference temperature
  • Dished dial (anti-parallax) for ease of reading
  • Adjustable stem and dial version enables optimal process connection
