WIKA Datasheet C-10
Description
The WIKA C-10 provides performance and economy for a
wide range of OEM applications. They are especially suited
to applications subject to severe mechanical shock, vibration
and electromagnetic interference. Typical applications
include hydraulics and pneumatics, compressor controls,
pump protection, refrigeration and air conditioning systems.
Dependable performance
The C-10 features an all-welded stainless steel measuring
cell for improved media compatibility. There are no internal
soft sealing materials that may react with the media or
deteriorate over time. The case is also made of stainless
steel and is available with environmental protection ratings
up to NEMA 4 / IP 67.
Pressure ranges up to 300 psi use a piezoresistive
measuring cell. The higher pressure ranges use thin lm
sensor technology. Both are time proven highly reliable
sensor technologies.

Right: C-10 with optional cable
A standard signal output of 4-20 mA allows the C-10 to be
integrated into many existing applications. Many custom
signal outputs, process connections and electrical
connections are available.
Each C-10 undergoes extensive quality control testing and
calibration to achieve an accuracy of < 0.50% full scale. The
printed circuit boards use state-of-the-art surface mount
technology. Each is individually temperature compensated to
assure accuracy and long-term stability even when exposed to
severe ambient temperature variations.

*Pressure applied up to the maximum rating will cause no permanent change in specications but may lead to zero and span shifts
**Exceeding the burst pressure may result in destruction of the transmitter and possible loss of media
