Macro Sensors LVDTs: R 1380 Series Rotary RVDT Position Sensors

产品介绍

This is a legacy product. We no longer produce the R1380, but we do have a small inventory still available.

The Macro Sensors R1380-050 are a series of contactless, fractional-turn, absolute output rotary position sensors that provide an analog voltage or current output proportional to shaft rotation over a total range of 100°. They are ideal sensors for measuring the position of quarter-turn ball and butterfly valves, flue dampers, weir gates, mail sorters, conveyor check weigher systems, dancer arm tensioners, and myriad other 应用领域 involving 90° shaft movement. The R1380 series is also useful for other limited rotation 应用领域 requiring high reliability like pedal position sensing for mobile equipment such as lift trucks, stackers, golf carts, and lawn tractors, or throttle lever position sensing in boats, cranes, and articulating-arm utility service vehicles.

The R1380 series of rotary position sensors utilize built-in electronics to offer several DC input/output configurations. They are available for 0° to ±50° rotation range with a ±10 V DC output, or for 0° to 100° rotation range with unipolar outputs of 0.5-4.5 V DC ratiometric, or 4-20 mA DC, either 3-wire sourcing or 2-wire loop powered. The sensors have electrical trimpots for fine zero and span adjustment of the DC output.

R1380-050 series rotary sensors utilize an anodized aluminum mounting flange with a 16 mm diameter center pilot and kidney-shaped mounting slots that permit coarse mechanical adjustment of about ±5° for 应用领域 measuring 90° rotation. These sensors are enclosed in a stainless steel shell, and have a 6 mm stainless steel shaft running in cost-effective sleeve bearings. Overall the units are environmentally sealed to IEC IP-66. Normal electrical I/O termination is a 12-inch (300-mm) long cable, but on special order for OEMs, longer cable lengths or a sensor-mounted connector can be supplied. Contact the factory for more information.

Mechanically, all R1380 series sensors are full 360° rotation devices with two 100° ranges having a 线性误差 less than ±0.25% of full range output located 180° apart. The sensors' principal rotary range is denoted by the alignment of the flat on the sensor's shaft perpendicular to a witness mark cast into the face of the mounting flange. In this position, the analog output decreases when the shaft is rotated clockwise as viewed from the shaft end. In the alternate 100° range, the output slope is reversed, so the analog output increases as the shaft is rotated clockwise. Their absolute output characteristic makes the R1380 series of sensors superior to incremental output sensors like optical encoders that lose their position information in the event of a power failure.
