Descrizione
These high-quality gauges are characterised by their compact and durable construction and are primarily for use in level measurement on liquid gas tanks.All the standard cryogenics tank sizes are covered using only 4 different measuring cells. As a result of the large measuring-range overlap of the respective measuring cells, the gauge installed on the tank can be adjusted to match a whole variety of gases such as Ar, O2, N2 or CO2, with a full-scale deflection over a complete 270 degree sweep. The span adjustment is accessible from outside and does not affect the zero point. The mechanical display and the optional electrical output signal are calibrated simultaneously and easily.An optional connectable valve block with working pressure display makes the central measurement of both level and working pressure possible in the one instrument.The level display can be supplied with an optional, integrated 4 … 20 mA, 2-wire transmitter. Limit signal transmitters for level and working pressure, as well as a transmitter for the working pressure can be retrofitted onsite.The standard connection distance between the process connections of 37 mm can be adapted to custom connection distances of 31 mm or 54 mm using connection adapters.
