Operating conditions
Operating temperature range (ambient temp.) –25 ÷ 80°C
Medium temperature range:
25 ÷ 120°C – direct measurement
25 ÷ 170°C – measurement using a impulse line

The transmitter is not heavy, so it can be fitted on
the installation. For pressure measurements of
steam or other hot media a si phon or impulse line
should be used. The needle valve placed u pstream the transmitter simplifies installation p rocess and enables the transmitter re pla cemen t.

Electrical parameters
Output signal

The acti ve sensing element is a piezo resistant
silicon sensor separated from the medium by a
diaphragm and by special ly selected type of
manometric liquid. The electronics are placed in
the casing wi th a degree of protection IP65. Electrical connection is the connector DIN 43650.
