DB-DA/DB-DC | Transducers for measuring radial forces in ball bearings

Product catalog summary

Overview: The Magtrol DB-DA and DB-DC series transducers are designed for measuring the radial load of ball bearings. They are suitable for applications such as belt, paper, or textile tension control and other radial force measurements on rotating cylinders.

Features:

Nominal Capacity: DB-DA models range from 50 to 750 N, while DB-DC is 1200 N.
Overload Protection: DB-DA offers up to 2x overload protection, while DB-DC lacks mechanical protection.
Combined Error: Non-linearity and hysteresis errors are less than ±0.1% (DB-DA-50 is < ±0.2%).
Temperature Ranges: Available in 0-60°C, 0-100°C, and 0-160°C.
Protection Class: IP 67, ensuring hermetic sealing.
Construction: Rust-resistant metallic build, easy installation.

Specifications:

Transducer Ratings: Nominal loads vary by model, with overload limits up to 2000% for DB-DA models.
Electrical Characteristics: Nominal sensitivity is 1 mV/V ±3%, with input impedance at 400 Ω and output impedance at 350 Ω.
Environmental Characteristics: Operating temperatures range from 0°C to 160°C, with specific temperature influences on zero and sensitivity.

System Configuration: The transducers can be connected to signal conditioners and displays such as the PSD Portable Sensor Display and LMU Series Load Monitor Unit for enhanced measurement and monitoring capabilities.

Ordering Information: The ordering code includes model type, nominal load, diameter, and temperature range. For example, a DB-DA transducer with a 350 N load, 17 mm diameter, and 160°C range is ordered as DB-DA-350-17-160.

Related Products:

LMU Series: Designed for load, force, and weight measurement, providing excitation voltage and signal conditioning.
AN Series: Load monitor display with integrated signal conditioner for processing and displaying transducer signals.

Accessories: Includes spare safety pins and cable extensions, with specific ordering numbers provided.
