EGE Sensor Identification, P-Number Part Codes & Technical Selection Guidelines

EGE-Elektronik Spezial-Sensoren GmbH (founded in 1976 and headquartered at Ravensberg 34, D-24214 Gettorf, Germany) specializes in advanced process sensors and rugged automation instrumentation engineered for harsh industrial operating environments across metallurgy, chemical processing, maritime

engineering, and food processing.

For precise identification of an authentic EGE sensor, flow controller, or limit switch, the primary identifier is the factory Part Number (P-number), structured as the capital letter P followed by a 5-digit numerical code (e.g., P11298, P10515, P21102, P30701).

The P-number explicitly determines the wetted material metallurgy, electrical connection pinout, housing thread geometry, and cable length.

If the housing engraving or label is corroded by harsh process chemicals, provide a clear photograph of the unit tag, the mechanical process connection dimensions, and operating process parameters (medium type, system operating pressure, process temperature range, and electrical output

specification).

Thermodynamic Flow Sensors & Inline Monitoring Controllers (SDN, SDNC, ST Series)

Unlike mechanical turbine, gear, or paddlewheel flow meters, EGE industrial flow sensors function on the solid-state thermodynamic (calorimetric) principle. The wetted sensing probe is heated slightly above the ambient temperature of the fluid medium.

Flowing liquid or gas absorbs heat from the sensing probe, and internal microprocessor circuitry calculates linear flow velocity from heat dissipation dynamics.

The complete elimination of moving parts prevents mechanical seizure from suspended solids, fibrous contamination, or scaling, ensuring uninterrupted long-term reliability in hydraulic power units, robotic welding torch cooling circuits, rolling mill bearing lubrication lines, and chemical batch

reactors.

The portfolio includes insertion immersion probes (ST 421 series) and inline compact flow meters (SDN 552/3 series) with integrated calibrated flow tubes for precision dispensing and flow limit monitoring across flow velocities from 1 mL/min up to 3 m/s.

Guided Microwave TDR Radar Sensors & Capacitive Level Detectors for Complex Media

For continuous level measurement in process tanks, mixing vessels, and silos, EGE engineers the MFP series guided microwave level transmitters based on Time-Domain Reflectometry (TDR).

High-frequency electromagnetic radar pulses travel along a rigid or flexible stainless steel waveguide and reflect directly off the liquid or bulk solid interface.

Continuous level readings remain impervious to changing fluid density, process operating pressure, severe steam, dust blankets, or condensation on silo sidewalls. Measuring probes up to 3 meters in length integrate directly into standard G3/4 or G1 tank connections.

For point-level overfill and dry-run pump protection, EGE manufactures MFK capacitive sensors and specialized high-temperature KGFT/KGFW probes that actively suppress coating and build-up from sticky slurries, viscous glues, hot asphalt, and polymer pastes up to +250 °C.

Inductive Proximity Switches for Heavy Industry: Tropical IP68/IP69K & IGH High-Temp Series

Conventional inductive proximity switches frequently fail when exposed to high-pressure washdowns, hot forging areas, and rolling mills. EGE develops specialized heavy-duty inductive sensor families designed to conquer these demanding industrial failure points.

The Tropical series features a vacuum-cast polyurethane or epoxy encapsulated housing rated IP68 for continuous underwater submersion up to 3 bar (30 meters water depth) and washdown IP69K resistance against aggressive cleaning chemicals and high-pressure steam cleaning.

The IGH and IGV series inductive proximity switches operate in ambient temperatures from -25 °C up to +250 °C without requiring bulky water-cooling jackets, ensuring dependable workpiece tracking and limit switching directly adjacent to industrial heat-treating furnaces.

Non-Intrusive Capacitive Proximity & Level Sensing Through Vessel Sidewalls (KD, KG, KGM)

EGE capacitive proximity switches in the KD, KG, KGM, and KGA series evaluate changes in electrical capacitance within the active sensing zone when any conductive or non-conductive object enters the electrostatic field.

This non-contact operating principle enables operators to monitor bulk plastic pellets inside hoppers, agricultural grain in storage bins, pharmaceutical powders in blenders, and chemical liquids inside transparent or translucent polymer tubing without tapping into pressurized piping.

Sensors feature multi-turn cermet potentiometers or digital Teach-in pushbuttons to calibrate out vessel wall thickness and ignore dry dust accumulation on the sensor face.

Flush Ceramic Diaphragm Pressure Sensors (DN Series) & Compact Temperature Units (TN Series)

EGE pressure transmitters in the DN and DNC series feature a dry flush-mounted capacitive measuring cell manufactured from ultra-pure aluminum oxide ceramics (Al2O3).

The flush diaphragm seats flat with the pipe wall, completely eliminating dead pockets and preventing clogging from fibrous pulp, sludge, or crystalline deposits.

High-purity Al2O3 ceramic demonstrates exceptional hardness and abrasion resistance against slurry erosion while enduring severe dynamic pressure spikes and cavitation shocks up to 40 times rated pressure without zero-point drift.

The TN and TDA series compact temperature controllers integrate a Pt100/Pt1000 sensor, bright digital display, and dual configurable switching outputs within an all-stainless G1/2 housing to protect industrial lubrication and hydraulic circuits from destructive overheating.

Hot Metal Detectors OD 100 & Optical Sensor Systems for Steel Mills and Heavy Processing

In hot rolling mills, continuous casting plants, and forging presses, standard optical sensors are rapidly blinded by airborne scale, intense water spray, and heavy smoke. EGE engineers the OD 100 series Hot Metal Detectors (HMD) specifically to operate in these punishing environments.

The sensor captures narrowband infrared radiation emitted by heated metal workpieces at temperatures from +250 °C up to +1000 °C and higher at operational standoff distances of several meters.

An ultra-fast response time below 1 ms ensures high-speed flying shears and roller tables remain synchronized.

The rugged stainless steel enclosure features a protective compressed-air purge collar to keep optics clean and can be equipped with an optional liquid-cooling jacket for extreme thermal radiant loads.

ATEX / IECEx Certified Explosion-Proof Sensors & Associated Galvanic Barriers

Automating process plants across oil and gas terminals, chemical synthesis reactors, fuel storage depots, and grain milling facilities mandates stringent explosion protection compliance. EGE produces a comprehensive lineup of sensors certified to European ATEX directives and global IECEx standards.

Apparatus is certified for deployment in hazardous Gas Zones 0, 1, and 2, as well as combustible Dust Zones 20, 21, and 22. Primary flow, level, and proximity sensors interface via intrinsically safe Namur circuits compliant with DIN EN 60947-5-6.

To connect field sensors with plant DCS and PLC automation systems, EGE supplies DIN-rail switching amplifiers, power supplies, and galvanic isolators in the SKM, SKZ, and SZA series installed in the safe control cabinet area.

Product configurations, production lead times, and international supply pricing for EGE instrumentation and accessories are established individually upon technical inquiry; the manufacturer does not maintain public retail pricing.

We conduct business as an independent B2B engineering distributor and do not represent ourselves as an authorized agent of EGE-Elektronik Spezial-Sensoren GmbH.
