3. Technical data and intended use

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
