When designing your plant, take into account that the stated values (e.g.burst pressure,
over pressure safety) apply depending on the material, process connection, fittings and
sealing element used.

tion classes specified only apply when the pressure transmitter is connected
with female connectors that provide the corresponding ingress protection
Weight
Approx. 0.5 kg (ca. 0.6 kg with option accuracy 0.25 % of span)
Functional test
Open pressure connections only after the system is without pressure!
Observe the ambient and working conditions outlined in section 7 “Technical data".
Please make sure that the pressure transmitter is only used within the over-
load threshold limit at all times!
The output signal must be proportional to the pressure. If not, this might point to a damage
of the diaphragm. In that case refer to chapter 10 “Troubleshooting“.
When touching the pressure transmitter, keep in mind that the surfaces of the
instrument components might get hot during operation.
