Pressure switch, high adjustability of switch differential
Description
The model PSM-700 mechanical pressure switch has been designed for control and monitoring applications. The measuring element is a fully welded bellow made of stainless steel 316L. This corrosion-resistant pressure switch is suitable for a broad range of media used in the process industry.
The case consists of a high-grade aluminium alloy with which the pressure switch can withstand the harsh operating conditions of the process industry.
The model PSM-700 is equipped with UL listed micro switches to ensure high endurance with durable operation and long service life.
Special features
- Switch differential adjustable within a wide range of up to 60 % of the setting range to realise flexible on/off controls
- Robust aluminium case
- Switch point repeatability of ≤ 0.5 % for reliable switching
- High-quality micro switches with long service life
- Up to 2 possible positions for electrical connection
