I am searching for a Temperature Transducer/Transmitter which will measure temperature from thermocouple or 2 wires RTD and which will provide 4 to 20 mA output ( as per temperature range 0 to 200 deg. C.) and which will provide alarm also if temperature goes beyond of set.

I found it in H & B product(TEU315 temperature transmitter) in their product list. But I want from another company which will be equivalent to HB TEU 315 Transmitter.

Could anybody suggest me where I can get this Temperature Transmitter/Transducer?

Dear Steve,
There are thousands of manufacturers who make such devices. The choice is so large that, you have to specify your location (north america/europe/asia) for narrowing the search. Please, do a Google search for shopping around.

The three manufacturers I've worked with very recently are

RKC, Japan

Autonics, Korea
http://www.autonics.com

Jenco, Taiwan

I am in Bangladesh, hence the asian bias! I'm sure there are many other companies doing these devices in other parts of the world.

By the way, RDTs are usually three-wire, right? Some are four-wire for higher precision. But I never encountered a two-wire RTD. It is indeed possible to make one, but the reading will be quite inaccurate due to cable resistance.

Probably ACROMAG USA * MOORE Industries, MTL would
meet your requirement completely.
