Those working with equipment are seeking the structural design for remote temperature (pressure) sensor connectors

Thread Content

I work with equipment but don’t understand automatic control; however, I’ve been given an electric heating kettle. The basic data of this kettle are as follows. Material name: Solid-liquid mixed slurry. Operating temperature: 260°C. Working pressure: 3.6 MPa. Equipment volume: 40 liters (ø350X450). For this medium-pressure equipment, the client requires remote temperature (pressure) sensing ports, yet no corresponding product manual is provided by the client. Excuse me, gentlemen. In such a situation, should one insist on obtaining from the client the relevant product manual, or the structural drawings showing the design of the connectors for remote temperature (pressure) measurement? I would like to ask the experts in automatic control. Are the connectors of these automatic control devices standard parts?

For remote temperature (pressure) sensing, the flange connection type is specified – whether it is threaded or flanged. For temperature measurement, a thermal resistor of DN25, PN2.5 is used; attention must be paid to the insertion depth and the measurement range. For pressure measurement, a pressure transmitter is installed. Just find a selection sample and it’s done.

The instrument interfaces on the equipment are generally connected using flanges. For the temperature measurement instruments, a flanged stub of DN40 PN6.4 can be used, while for pressure measurement instruments, a flanged stub of DN25 PN6.4 is suitable; the connection method for the instruments is then determined based on the interface type available on the equipment.

For the temperature measurement points, flange-connected thermal resistance protection sleeves should be used, with the flanges located on the equipment itself; care should be taken to select an appropriate insertion depth so that the desired temperature can be measured. Select the appropriate thermistor by considering the specifications of its protective sleeve.

If the instruments are supplied by you, then install them for them. If the instruments are supplied by them, ask them for the instrument connection type and interface dimensions. If the owner refuses, follow the method used on the 3rd floor.
