Description
The connection head of the PIH or PIR series is available with various explosion protection certifications for different ignition protection types. The fitting of different terminal blocks or transmitters is possible. A window in the upper body of the case enables the fitting of a digital display for the on-site display of the measured value. With the optional wall or pipe-mounting brackets, vertical or horizontal mounting in the field is possible. High-quality surface coatings also enable operation in harsh environments.
Internal grounding and external equipotential bonding terminals make the field cabling simple and easily accessible.
