PT300 temperature transmitter-conical probes

發(fā)布時間：2013-08-06

 

Feature and usage:
Temperature transmitter is suitable for high temperature melt and liquid and gas’ temperature measurement. The sensitive part uses the conical shell, whose depth is customized, probes is placed in measuring medium, making it more accurate, less operating time, easy to use. Widely used in petroleum, chemical, rubber, plastic, water treatment, medicine, food and other industries.Characteristic: high precision, stainless steel package, easy installation, to replace the similar imported product, 80% internal calibration stability, good repeatability performance
Index：

1：conical probes design,

2： 0…0.1bar to 0…2500bar pressure measuring.

3:connector or directly connect.

4：various pressure interface.
