User Manual - P series Introduction You have just acquired a GEORGIN instrument that has undergone extensive testing and several quality checks to ensure your complete satisfaction. Appropriate specification, according to your process, and compliance with the instructions in this manual will ensure an optimum working life for your instrument.
Page 4 User Manual - P series Qualified equipment in accordance with RCC-E The pressure switches and temperature switches of the P series meet the design and construction rules for electrical equipment of nuclear plants. Refer to the equipment identification sheet (according to the last index NTP N 100 – consult us) for a definition, installation rules and recommendations for maintenance of the equipment in accordance with the associated quality and general requirements.
Page 5: Before Installation
User Manual - P series For temperature switches, the minimum dead bands given in our manuals are recorded under ideal test conditions. The sensing element experiences the temperature variations of the installation without delay and in its bulk. In operation, these dead bands can be different in view of the exchange conditions: rate of temperature change, specific heat, radiation, inertia of the measuring instrument compared to inertia of temperature switch, presence of a sleeve or immersion sleeve, etc.
Page 6: General Recommendations
1.7. Vibrations Georgin recommend avoid mounting the instrument directly on vibrating equipment. Otherwise, an effective anti-vibration system, fully suitable for installation (assembly type, process connection, electrical connection, ...) and its environment, must be chosen.Flexible piping connections and silent blocks may sometimes be necessary.
Page 7: Special Recommendations
User Manual - P series 1.8. Mounting the housing (see Chapter IV.1) Georgin recommends mounting the housing in accordance with the following rules: a. For bellows or Bourdon tube pressure switches and temperature switches: The orientation of the housing has little effect on the operation of the instrument, but an upright (vertical) position is nevertheless recommended (with adjustment screw facing upwards).
Page 8: Prohibited Actions
User Manual - P series 2.4. Bourdon tube instruments (PL/PLB sensors) When the instrument is mounted on rigid fittings, ensure that the mount does not apply any residual loads to the process connector. 2.5. Temperature switches Any difference in level between the housing and the probe must be taken into account. Where necessary, to inhibit the effect of the height of the liquid column, the calibration values may need to be corrected (for more information, ask us).
Page 9: Mounting The Housing
(D)MABV - DMKBV: Use the two M10 threads provided under the sensing element. (D)MJBV - (D)MPB: Use the two M6 threads provided under the sensing element. We also provide special mounting brackets for the purpose. Ask Georgin for further information. www.georgin.com...
Page 10 User Manual - P series 2. Mounting Avoid mounting on a vibrating wall. This may result in a premature electrical malfunction. It is especially when approaching the changeover thresholds that our devices are particularly sensitive to certain vibration frequencies. If no other mounting is possible, we recommend the use of elastic suspensions for any use on a vibrating wall, especially in the case of a slow evolution of the pressure or temperature.
Page 11 User Manual - P series 2.2. Temperature switch mounting Observe the environmental and fluid-related conditions corresponding to the characteristics of the instruments. Never exceed the maximum temperature of the instrument indicated on the label on the side of the housing. A capillary introduced into the liquid can be of any length.

Page 21 IMPORTANT Intrinsic Safety certified instruments (Ex ia) are equipped with gold-plated contacts. These instruments must be interfaced via an Intrinsic Safety relay. Georgin recommends the RDN model - see fc-rdn-fren on www.georgin.com. The explosion proof switches with cable output must be imperatively connected to an approved terminal block and a junction box.
Page 22: Maintenance
» The mechanical working life of the sensing element » Frequency and conditions of operation of the instrument Georgin's standard* recommendation is to proceed as indicated: 1. Visual inspection of the instrument 1. Visual inspection (See Chapter II. Before installation) 2.
