These battery-powered devices, which are fitted with a piezo-resistive sensors, resist overloads up to three times nominal loading.
There is a choice between 25 measuring ranges, which extend from -1 ... 0 up to 0 ... 2000 bar. The manometer can be installed in such a way that the easy-to-use four-digit LCD display can be very easily read, as both the process and connection and the front cover are rotatable.
Operation is simple and convenient using three functions on the film-covered keypad. The zero point can be set automatically using the zero function, and a freely-selectable password offers protection against incorrect or unintentional operation.
Models with analogue or relay output are available. In the model with a push button and relay, switching point and hysteresis can easily be set using the keypad. The devices can also be provided with a peak value memory.
This robust pressure measuring device fulfils Protection Class IP 65 ist and is therefore suitable for use in tough applications. All parts which have contact with media are of stainless steel or ceramic.
