The 330100‑50‑02 is a Proximitor (proximity sensor / transducer module) designed to work with eddy‑current probes and extension cables in rotating machinery monitoring systems. It is part of the family that forms the interface between the probe and the monitoring/control electronics, conditioning the raw signal and providing a stable output to the monitoring system.
The “50” in the part number suggests a 5.0 meter (or equivalent) cable or total assembly length, and “02” indicates that the model includes certain agency or safety approvals (or particular connector options). The module is engineered to provide stable, linear output over a defined measurement range, even under adverse industrial conditions. It is used in vibration/shaft displacement monitoring in power plants, turbines, compressors, pumps, and other critical rotating equipment.
This module is typically used in conjunction with the 3300/3300 XL proximity transducer system, and supports high reliability in conditions of temperature, humidity, and electrical noise.

Notes on Dimensions & Weight
The housing dimensions (approx. 81.3 × 50 × 63.5 mm) represent the module body excluding protruding connectors.
The weight is approximate and includes the module and minimal internal wiring, not the entire cable assembly.
Because public detailed datasheets for 330100‑50‑02 are scarce, these values are inferred from known “330100‑50‑xx” family modules and standard conventions.
The 330100‑50‑02 module is used in industrial settings where continuous monitoring of shaft vibration, position, or a combination is essential. Typical applications include:
Steam turbines, gas turbines, and hydro turbines
Compressors, centrifugal and reciprocating
Rotating machinery in petrochemical / oil & gas plants
Generators and auxiliary rotating equipment
Pumps, fans, blowers in harsh industrial environments
Machinery protection systems, condition monitoring, diagnostic analytics
High‑vibration, high-humidity, or temperature-stressed locations
It integrates with a proximity probe and extension cable to deliver conditioned signals to monitoring systems that perform alarm, shutdown, or trend analysis.
✅ Stable Signal Conditioning: Offers reliable, linear output with minimal drift over temperature.
✅ Compatibility: Works with standard eddy-current 3300 / 3300 XL probes and extension cables.
✅ Rugged Design: Housed in industrial-grade aluminum for protection against vibration, moisture, and mechanical stress.
✅ Safety & Approvals: The “02” suffix likely indicates built-in agency compliances (e.g. intrinsic safety or explosion-proof variants).
✅ High Humidity Tolerance: Designed to operate in 100% relative humidity if connectors are sealed properly.
✅ Compact & Field-Fit: Small size and moderate weight allow easy mounting near rotating equipment.

Q1: What is the role of the 330100‑50‑02 in a proximity sensing system?
A1: It conditions and translates the raw signal from an eddy-current probe into a stable output suitable for monitoring systems, bridging between the probe and the data acquisition or protection logic.
Q2: Why does the part number include “50” and “02”?
A2: “50” typically refers to the nominal cable or assembly length (5.0 m), while “02” often denotes a variant including particular safety approvals or connector configurations.
Q3: Can this module operate in very humid conditions?
A3: Yes — if the connectors are properly sealed, it is rated for 100% relative humidity (non‑submersible).
Q4: What voltage does the module require for operation?
A4: It typically needs a supply in the range of –17.5 Vdc to –26 Vdc at up to 12 mA.
Q5: Is this module suitable for extremely high-temperature environments?
A5: Its operating range (–51 °C to +100 °C or similar) is suitable for many industrial settings; for extreme heat, verify compatibility with the equipment environment.
Q6: How precise is its output?
A6: It is designed to maintain linearity and stable sensitivity across its specified measurement range when paired with compatible probes.
Q7: What happens if the connector seal fails?
A7: Moisture ingress or contamination can degrade signal quality, reduce insulation resistance, or cause drift — hence correct sealing is essential.
Q8: Can this module be mounted remotely or in a control room?
A8: It is better placed near the probe to minimize cable noise; long-distance mounting may require additional design considerations to maintain signal integrity.
Q9: Does the module need calibration?
A9: The internal electronics are factory-calibrated; however, the integrated system (probe + module + monitor) may require periodic system-level verification or calibration.
Q10: How often should this module be inspected or replaced?
A10: Regular visual and electrical inspections (e.g. yearly) are recommended. Replacement is often warranted when drift, insulation degradation, or connector failure is detected.
