6.16.9 Pressure terminals, aggressive media
The eight measurement input nipples allow the measured substances to be hooked up directly and easily
via quick-release couplings. An optional low-leakage model is available.
The properties of the sealing materials can be
adversely affected by chemical and temperature
processes. When selecting sensors, connector
nipples, and couplings, be aware of the measured
materials' chemical properties (see Chapter
General technical specs ). The temperature
limits are also noted in Chapter General technical
specs . The nipples' shape and material are of
particular importance. For instance, nipples of
brass and stainless steel are available. The type
and material of the sealing gasket are also crucial
and must be suitable for the medium to be
measured.

All specifications are for orientation purposes only and no responsibility is taken for their correctness.
They are meant to apply to 1) pure substances, 2) unless otherwise indicated, at room temperature, 3)
for saline solution, acids and aqueous solutions, moderate concentrations.
