Accuracy @ 25 °C** Ranges A and B: ±1% F.S. typical***;
Range C: ±1.5% F.S. typical***;
Range D: ±2% F.S. typical***
*VFD systems and system wiring generate fields that can disrupt electrical devices. Ensure
that these fields are minimized and are not affecting the sensor or sensor wiring.
**Accuracy combines linearity, hysteresis, and repeatability.
*** FS is defined as full span of selected range in bi-directional mode.
EMC Conformance - Low voltage directive 2014/35/EU; EMC directive 2014/30/EU.
EMC Special Note: Connect this product to a DC distribution network or an AC/DC power
adaptor with proper surge protection (EN 61000-6-1 specification requirements).
The PW Series wet pressure transducers incorporate microprocessor
profiled sensors for exceptional accuracy and reliability. Easy to use
and designed to provide exceptional installation savings, the PW Series
is ideal for measuring pressure across pumps, filters, heat exchangers,
compressors, and other non-corrosive wet media applications.
The DIP switch selectable port swap feature eliminates costly
replumbing when the high and low ports are improperly plumbed,
allowing the DIP switch position to be changed from normal to swap.
The optional pre-assembled bypass valve is designed for easy
maintenance and one-step installation.
