P Series

Product catalog summary
Introduction
The document introduces the P Series of pressure and temperature switches by Georgin, designed for precision and reliability in industrial applications. These switches are suitable for harsh environments and are used in industries such as energy generation, metallurgy, chemicals, and shipbuilding.
Specifications
The P Series offers control for gauge, absolute, or differential pressure and temperature through direct bulb or capillary. They provide electrical contact or pneumatic signal output and are designed for explosive atmospheres (ATEX) with explosion-proof enclosures and intrinsic safety features. The equipment complies with pressure equipment directives (PED) to prevent exceeding allowable limits.
Construction
The switches are available in standard and explosion-proof housings, made from materials like zamak and aluminium. They feature stainless steel fittings and various sensing elements such as bellows and diaphragms, suitable for different pressure conditions. Operating temperature limits vary by material, with stainless steel components handling -40 to +150°C.
ATEX Equipment
The document details certification and safety features for equipment used in explosive atmospheres, including intrinsic safety, increased safety, and explosion-proof safety. It specifies installation areas, equipment categories, and maximum surface temperatures.
Electrical and Pneumatic Functions
Georgin's switches use SPDT electrical contacts with options for fixed or adjustable dead bands. They offer various electrical functions, including manual reset and explosion-proof contacts. Pneumatic functions are available with normally open or closed configurations, using poppet or spool valves.
Applications
The P Series is applicable in thermal and nuclear energy generation, metallurgy, chemicals, petrochemicals, textile industry, and more. It is also used in gas, steam, or hydraulic turbines, diesel engines, pumps, compressors, and shipbuilding.
Certifications and Qualifications
The switches are qualified for various industrial standards and applications, ensuring reliability and safety in demanding environments.
Operational Specifications
The instrument ceases to function at ambient temperatures below +6°C but resumes normal operation without damage once temperatures rise above this threshold. Special temperature ranges can be requested to increase maximum operational temperatures. Probes should be installed vertically or at an angle up to 45°, with specific considerations for angles up to 75° and consultation required for angles beyond 75°.
Dead Band Values
The document specifies minimum and maximum dead band values for temperature variations, with adjustments for explosion-proof housings. These values are based on optimal test conditions with fully immersed bulbs.
Bulb Design and Capillary Length
Bulb dimensions and materials vary based on capillary length, with standard lengths provided. The WX range has a fixed bulb length of 14.150 mm.
Installation Recommendations
Immersion pockets require a thermal bridge for gaseous applications. Probes should be installed facing down, with capillary outlets at the top, and should not be placed horizontally. The document outlines the impact of probe inclination on operation, recommending a range of ±45° from vertical.
Capillary Cable Gland and Protection
Capillary cable glands ensure tightness and are standard on certain models. Additional protection options are available.
Dimensional Drawings
The document includes references to dimensional drawings and notes on instrument mounting requirements.
Certification and Compliance
The P series pressure and temperature switches comply with various certifications, including Directive 2014/34/EU for explosion risk areas, PED 2014/68/EC, TR CU for the customs union, marine certification, NATO accreditation, and NACE compliance. Specific qualifications for nuclear equipment are also mentioned.

Maximum breaking capacity (resistive load) Pneumatic function type The control fluid must be compatible with the ISO-VG 10 standard (air, nitrogen, etc.). Maximum allowable filtration 5 pm. The standard materials for the cell body are polyamide, brass, and/or aluminium. The seals are made of NBR (other types on request). For certain models, exhaust is via open cable gland or screw terminal (mandatory for ATEX models). The control pressure applied to the unit affects the dead band: the lower the supply pressure, the smaller the dead band, and vice-versa. POTENTIOMETRIC FUNCTION Resistive-type...

PX denotes a P series gauge pressure switch. For the sensitive element of P . PX with stainless steel bellows, the maximum pressure is 15 bar Its scale is 0.5 to 10 bar, which means that a setpoint can be adjusted when the pressure drops to between 0.5 and 10 bar. Please note that the setting range for a pressure rise setpoint is dependent on the associated microswitch. Note: the adjustment plate is indicative (accuracy...

Important remark on probe installation operation of Beyond this Thermostatic probes must be installed facing down, with the capillary outlet at the top. The measurement probe must not be placed in a horizontal position. The position of the probe can affect the the temperature switch. This type of probe is intended for vertical use, and is placed lower than the housing. Any deviation from these conditions can affect the response time and operation of the device. By design, our temperature switches are filled to allow probe inclination of 45° without affecting operation. value, operation is dependent...
