Eddy Current Displacement Sensor MTN/EP080
- Manufacturer: Monitran
- Category: Displacement, Eddy Current, SENSORS
Eddy current sensor for measuring proximity and radial vibration of metal shafts without contact. Linear range from 0 to 2 mm, nominal sensitivity of 8 mV/µm, linearity of 1% (nominal). Applications: turbomachinery, eccentricity and clearance in oil-film bearings.
Frequency response from DC (static position) to 10 kHz (dynamic vibration). Output impedance <50Ω. Power supply: -24V DC at 30mA (negative supply). Calibrated with AISI 4140 steel.
Peek tip. Stainless steel body with M8 thread (6mm probe diameter). Probe temperature range: -30°C to +180°C; driver temperature range: -20°C to +80°C. RG179 cable with PTFE insulation, up to 9 meters, for MTN/6000 series racks or PLCs powered by -24V DC.
- Non-contact measurement, 8 mV/µm.
- Probe temperature from -30°C to +180°C.
- Stainless steel body with M8 thread.
- DC response up to 10 kHz.
Technical Frequently Asked Questions
1. Why is it powered by -24V DC?
The Eddy Current proximity sensors in this series are powered by -24V DC (at 30mA, negative supply).
2. What does the Peek material contribute to the printhead?
The tip is made of PEEK (high-performance engineering thermoplastic). The probe operates from -30 °C to +180 °C.
3. How does the shaft (target) material influence it?
The measurement depends on the conductivity of the material; the sensor is calibrated for AISI 4140 steel. With other materials, the sensitivity changes and a specific calibration adjustment is required.
