Questions & Answers
Does it come with hygienic approvals? (1 answer)
The Thermophant TTR31 comes with hygienic approvals along with various other certifications. The device meets the legal requirements of the EC directives and so gets a CE mark. It follows the various IEC, NAMUR, and NEMA standards and guidelines as well. As for the hygiene standard, the TTR31 temperature switch satisfies the requirements of the Sanitary Standards and Endress+Hauser confirms this by giving ti a a 3-A symbol hygienic approval.
What is the measuring principle of the Thermophant TTR31? (1 answer)
The temperature switch consists of a bimetal switch and a sensor. Generally, the change in temperature will make the bimetal deflect and kill the circuit, i.e when the temperature increases, the bimetal heats up until a temperature where it deflects and thereby opening up the electrical contacts and when the temperature drops, the bimetal returns to its original state and closes the electrical contacts. A platinum sensor is located at the measuring tip that changes its resistivity depending upon the temperature value. This resistance value is recorded electronically.
What are the process connections that the device comes with? (1 answer)
The device comes with threaded connections- G 1/2 ", G 1/4 ", and ANSI NPT 1/4 " and NPT 1/2 ".
