MTN/1187 Acceleration Transducer
- Manufacturer: Monitran
- Category: Accelerometers and Vibration Sensors, SENSORS
MTN/1187 top-entry acceleration transducer. It integrates a piezoelectric sensing element and a conditioning circuit. It provides a 4-20 mA DC current loop output proportional to the RMS acceleration (g), for direct connection to a PLC or data acquisition system.
Frequency response from 2 Hz to 1 kHz (±10%). Factory-configurable measurement ranges: 0-1, 0-2, 0-5, 0-10, or 0-20 g RMS. Power supply: 12 to 32 V DC (24 V nominal), two-wire.
Stainless steel housing with IP67 protection rating (IP68 optional). The base is galvanically isolated from the internal circuitry. Application: monitoring of bearings and mechanical components.
- 4-20 mA proportional RMS output.
- Frequency response 2 Hz to 1 kHz.
- IP67 stainless steel body, with galvanically isolated base.
- Versions: MTN/1187 (connector), MTN/1187C (cable), MTN/1187W (IP68), MTN/1187IC (ATEX / IECEx).
- Operating temperature: -25 °C to +90 °C.
- Mounted resonance: 5 kHz.
- Maximum dynamic range: 50 g (peak).
- Mounting torque: 8 Nm.
Technical Frequently Asked Questions
1. What is the maximum load impedance supported by the loop?
It depends on the supply voltage. With a 24V DC supply, the maximum load resistance (cable and PLC included) is approximately 600 Ohms.
2. What technical differences exist compared to the MTN/1185 series?
The 1185 series incorporates an integrator circuit and delivers a signal proportional to speed (mm/s). The MTN/1187 delivers a signal proportional to acceleration (g).
3. Is the MTN/1187 suitable for continuous immersion?
The standard model has IP67 protection (temporary immersion). For pumping or permanently flooded areas, there is the MTN/1187W variant, with IP68 sealing and a reinforced polyurethane cable.
