Overpressure safety: 40, 100; 50 or 400 bar
Process connection
In accordance with the general technical regulations for pressure gauges

(i.e. EN 837-2 „Selection and installation recommendations for pressure
gauges").
When screwing gauges in, the force required for this must not be applied
through the case, but rather through the spanner flats (using a suitable tool)
provided for this purpose on the square shaft of standard connections.
Temperature effect
When the temperature of the measuring system deviates from the reference
temperature (+0 °C): max. ±0.5 %/10 K of full scale value
IP Ingress protection
IP 54 per EN 60 59 / IEC 60 59
(with liquid filling IP 65)
