Datasheet torque sensor DRFS

Product catalog summary

Overview:
The document provides technical specifications for the DRFS and DRFS-I-w torque sensors manufactured by ETH Messtechnik GmbH. These sensors are designed for use in motor vehicles, test benches, and assembly technology, with optional angle measurement functionality.

Specifications:

Torque Ranges: DRFS offers 7 ranges from 1 Nm to 20 Nm, while DRFS-I-w offers 6 ranges from 0.5 Nm to 20 Nm.
Drive Type: Hexagonal drive suitable for pulse tools.
Power Supply: Single power supply with a voltage of 12 V DC ± 10% and current consumption of less than 200 mA.
Output: Voltage output ranges from 0 to ±5 V with an internal resistance of 100 Ω.
Accuracy: Nonlinearity is less than 0.15%, and hysteresis is less than 0.1%.
Temperature Range: Operating temperature is between 0°C and 60°C, with a compensated range of 5°C to 45°C.
Protection: Internal protection rated at IP40.

Features:

Contactless data acquisition eliminates the need for service.
High accuracy achieved through frequency modulation and strain gauge technology.
High noise immunity due to amplified active signal.
Integrated sensor-detection chip for use with GMV2 analyzer.

Mechanical Dimensions:

DRFS: Dimensions are 62 mm (A), 32 mm (B), 51 mm (C), 16 mm (D), 115 mm (E), 22 mm (F), 31 mm (G), with a weight of approximately 300 g.
