Nagano Keiki KH41 Manual

B03-02-J
Cat.No.
KH41・ 43, KD41・ 43
Process Applications
Pressure Transmitter
Outline
On-site type pressure transmitter for process use.
Since it is for general applications and proof
pressure explosion-protected use, select the type
corresponding to the working environment.
Features
Since the sensor uses a semiconductor strain
•
gauge, durability and stability are excellent.
Sinse the wetted parts use a high
•
corrosion-resistant metal diaphragm, corrosion
resistance is excellent and use with a wide range
of gases and liquids is possible.
EMI countermeasures have been taken so that
•
transceivers and other electronic devices are not
affected.
