Description

The model TG53 bimetal thermometer has been developed and manufactured in accordance with the ASME B40.200 standard. The thermometer provides high quality and performance, and is an ideal choice in the process industries.

The robust, hermetically sealed case with standard IP66 (NEMA 4X) ingress protection enables use within harsh external conditions.

Specifically designed for use in the chemical and petrochemical, oil and gas, power engineering and shipbuilding industries, the TG53 satisfies the rigorous requirements for resistance to aggressive media. As an available option, the case, stem and process connection can be made from 316 stainless steel.

For further approvals see page 6

The TG53 offers the widest variety of dampening options in the industry, allowing it to operate in situations where severe vibration conditions exist. These options include case filling and a damped bearing bushing to minimise pointer oscillation.

An easily accessible reset screw on the back of the case allows quick, limited reference temperature adjustment, reducing maintenance and recalibration costs.

The TG53 is also available in an assortment of stem lengths (insertion length L1 ) to optimise its application-specific fit and performance.

Special features

  • Robust, hermetically sealed case
  • Accuracy: ±1 % of full scale value ASME B40.200 (grade A)
  • External reset for setting the reference temperature
  • Dished dial (anti-parallax) for ease of reading
  • Adjustable stem and dial version enables optimal process connection
