Page 15: Installation
W601100880_A - Installation Installation WARNING: NOT FAIL-SAFE DESIGNED Risk of death. Do not use the Barocel 7025M for safety critical applications. The gauge is not intended to be fail-safe. CAUTION: IMPACT DAMAGE Risk of damage to equipment. The ceramic sensor can be damaged by impacts. Do not drop the gauge. - Page 16 W601100880_A - Installation 1. Position the gauge to prevent vibrations. Note: The gauge can be installed in any orientation. We recommend you install the gauge in a horizontal to upright position and use a seal with a centring ring and filter to prevent the influx of condensates and particles in the measurement chamber.
