7.5. Mechanical Vibration shocks. Corrosive Media
7.5.1. Transmitters should correctly work with vibrations with amplitudes to 1.6 mm and accelerations to 4g.
If strong vibrations are carried via the pressure line and disturb of measuring, use should be made of elastic
pulse lines or transmitters with a remote diaphragm seal.
7.5.2. Transmitters should not be installed in places where the diaphragm, made of 1.4404/1.4435 (316L)
steel, would be subject to corrosion by the medium being measured. If possible, transmitters with
diaphragms made of Hastelloy C276 should be used, or other means of protection applied (e.g. in the
form of a separating liquid) or transmitters with diaphragm seals adapted for measuring aggressive
mediums according to “DIAPHRAGM SEALS” catalogue cards should be used).
8. INSTALLATION AND MECHANICAL CONNECTIONS
Exd transmitters and 1/2 "NPT threads transmitters can be provided to the user with the fitted transport
plugs in place of the plug and cable gland.
In that case, remove the transport plugs and install the appropriate cable gland and plug before installing
the transmitter.
The APC..., APR... transmitters can operate in any position.
When installed on an object with a high-temperature medium, it is advantageous to mount the transmitter
in a horizontal position or downwards, in such a way that the transmitter is kept away from the rising hot
air.
For the small measurement ranges, the reading can be affected by the transmitter position, and by the
impulse lines configuration, or the way in which they are filled with liquid. This error can be corrected
using the zero-setting function.
8.1. APC... Installation and connections
8.1.1. The APC... transmitters can be mounted directly on the rigid impulse lines.
For used connectors as in Figures 5a, 6a and 7a, it is recommended that connection sockets be used as shown
in Figure 6b, 7b, 8b or 8c. It is recommended that sockets labelled “Socket CG1” and „Socket CG1/2” Fig. 9 are
used for CG1 and CG1/2 connections, respectively.
Besides, there are adapters for standard DIN50, (DIN40, DIN25, Clamp2”, Clamp1.5”, Clamp1”) type connections
provided for readouts carried out in aseptic conditions using transmitters with CM30x2 connection.
There are gaskets provided for every transmitter with P, CM30x2, CG1, CG1/2 and GP type connections.
The gasket material is selected based on the pressure value, temperature and the type of the medium.
8.1.2. If the pressure is applied via a flexible plastic tube, the transmitter should be mounted on a support with
Red Ø6-M reduction.
The types of the impulse tubes (Fig.25) are to be selected depending on the pressure measured value and
the medium temperature.
8.1.3. Tighten the transmitter in the socket with a torque suitable for the type of the gasket used and
the pressure measured.
8.1.4. The APC… transmitter can be installed using a universal “AL” holder allowing to mount the transmitter
in any position on the support or a horizontal or vertical pipe Ø35... Ø65 (Fig.17).
