WEZ 80-4 and WEZ 1/5-4 Digital Energy Meters
Weigel WEZ 80-4 and WEZ 1/5-4 microprocessor-controlled DIN-rail energy meters measure active and reactive electrical energy in low-voltage distribution boards. Designed for direct connection up to 80 A or indirect current transformer coupling (1/5 A), they provide high measurement stability.
- Direct current measurement up to 80 A or instrument transformer operation via 1/5 A CTs
- Integrated SO pulse output conforming to DIN EN 62053-31 for remote energy telemetry
- Compact 4-module DIN-rail enclosure with lockable and sealable terminal cover shields
- Multi-tariff energy registers backed by non-volatile flash memory for power continuity
AU, VU and Series 5.0 Measuring Transducers
Weigel AU, VU, AUD, VUD, and Series 5.0 transducers convert AC/DC currents, voltages, electrical power, and frequencies into standardized DC signals (4–20 mA, 0–20 mA, 0–10 V). Featuring galvanic isolation up to 4 kV, they deliver clean telemetry to supervisory control systems.
- True proportional conversion of electrical parameters into standard 4–20 mA or 0–10 V signals
- Three-port galvanic isolation safeguarding inputs, outputs, and power auxiliary circuits
- Series 5.0 specialized architecture engineered for DC voltages up to 1000 V CAT III
- Slim 22.5 mm DIN-rail packaging optimizing space across switchboard instrumentation tiers
Weigel Grenzsignalgeber Limit Value Relays
Weigel Grenzsignalgeber limit value monitors operate as precision two-step controllers to supervise current, voltage, and industrial telemetry. Built around a closed-circuit de-energizing principle, the relay trips instantly whenever measured electrical signals drift beyond defined threshold limits.
- Optical limit pickup scanning adjustable target pointers across the analogue indicator scale
- Flexible contact schemes offering Min/Min, Min/Max, or Max/Max potential-free SPDT relays
- Fail-safe closed-circuit relay response safeguarding heavy current motors and generators
- Couples with external transducers to monitor phase angle, grid frequency, and active power
DIN 43703 Measuring Shunts and Current Transformers
Weigel Nebenwiderstände precision measuring shunts manufactured to DIN 43703 extend the DC current measurement ranges of switchboard ammeters up to 15,000 A with calibrated voltage drops of 60 mV or 150 mV. High-grade manganin resistance bars ensure exceptional thermal and electrical stability.
- Calibrated current ratings from 1 A to 15,000 A with nominal voltage drops of 60 mV or 150 mV
- Precision manganin alloy resistive blocks ensure minimal temperature coefficient drift
- High accuracy class 0.5 engineered for heavy industrial electrolysis and DC drive systems
- Complementary bushing and split-core current transformers for high-voltage AC circuits
Electrical Measurement Technology Lineup of Weigel Meßgeräte
Weigel Meßgeräte GmbH manufactures DIN-compliant moving-iron and moving-coil panel meters, measuring transducers, and digital power meters for industrial switchboards.
Engineered for low and medium-voltage substations, marine distribution switchgear, and heavy industrial panels, these instruments deliver dependable accuracy under continuous operation.
The portfolio encompasses quadratic EQ and PQ indicators in 48x48, 72x72, 96x96, and 144x144 mm dimensions, WPM 770 multifunctional monitoring units with modular communication options, and precision manganin shunts according to DIN 43703 for DC current measurement up to 15,000 A.
Switchboard Instrument Sizing and Measurement Transducer Selection
Selecting Weigel instrumentation requires defining measured parameters (AC/DC voltage, current, active/reactive power), scale graduation, DIN housing dimensions, and auxiliary power options.
For rapid visual overview in main distribution switchboards, moving-iron EQ and moving-coil PQ pointer meters provide clear reading with interchangeable scales.
When integrating telemetry into automation networks, the WPM 770 power monitor or AU/VU signal transducers with 4 kV galvanic isolation deliver standard 4–20 mA loops or Modbus serial communications.
SpareX engineering teams verify current transformer ratios and instrument burden to optimize switchboard deployment.
