Pressure limitation
Model 73x.51/31: Steady: full scale value
Fluctuating: 0.9 x full scale value
Table 1: Max. working pressure / Overpressure safety maximum in bar
Model 73x.14: Steady: full scale value
Fluctuating: 0.9 x full scale value
Overpressure safety: 40, 100, 250 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 (+20 °C): max. ±0.5 %/10 K of full scale value
IP Ingress protection
IP 54 per EN 60 529 / IEC 60 529
(with liquid filling IP 65)
