700.01 Differential pressure gauge with magnetic piston WIKA

Description

The 700.01 differential pressure gauge with magnetic piston from WIKA is used for pressure measurement of gaseous and liquid media.

Model 700.01 is mainly used for monitoring differential pressures, even at high operating pressures, in the gas and air preparation and supply industry.

The separating membrane version of the model 700.02 is designed for liquid media and is therefore suitable for the water treatment and supply industry.

The compact and modular design of these differential pressure gauges allows for subsequent exchange of the measuring system and scale, as well as retrofitting and adjustment of the reed contacts on site.

The flange for mounting on the plate can be retrofitted to the 700.01 model.

Although these models have considerable overload protection up to maximum operating pressure, the weight of the standard versions with approx. 220 g in the case of model 700.01 and approx. 500 g in the case of model 700.02. This provides an economical and flexible solution for your measurement tasks.

This compact design with stainless steel measuring system offers an optimal price/performance ratio.
