Overview

Buy a rotary torque sensor for engine, with optional capacities ranging from 20 Nm, 50 Nm, 100 Nm to 5000 Nm. SUCH rotary torque sensors feature flanged input and output connections, eliminating the need for bearings. They are suitable for applications with high speeds or short shafts, such as engines, motors, generators, and other rotating power equipment. The non-contact torque transducer boasts a sensitivity of 1±0.2 mV/V and a stability of 0.3%F.S/year. It also has an IP65 protection rating, making it highly responsive and durable. Torque sensor capacity can be customized according to customer requirements. You can purchase a signal converter with 4-20mA/ 0-5V/ 0-10V output or RS485 communication for use with the rotary torque sensor.

Feature

Rugged and Durable: The housing is made of alloy steel, has an IP65 protection rating, and can withstand a safe load of 150% F.S.
Portability of Use: Continuously measures forward and reverse torque without repeated zeroing. It can measure both static and dynamic torque.
Easy to Install: The rotary torque sensor for engine features a double-flange structure, making it compact, lightweight, and easy to install.

FAQ

Q1: What is a rotary torque sensor? ❯

A rotary torque sensor is a device used to measure the torque applied to a rotating shaft. It converts mechanical torque into an electrical signal for monitoring and control in systems like motors, gearboxes, or pumps.

Q2: How often should you recalibrate a torque sensor? ❯

Torque sensors are typically recalibrated once a year, but the interval may be shorter if the sensor is used frequently, under heavy loads, or in harsh environments. Regular calibration ensures accuracy and reliability.

Q3: What factors can affect the output signal of a torque sensor? ❯

Shaft eccentricity or improper installation, vibration or mechanical shock, temperature fluctuations, electromagnetic interference or power supply fluctuations, and sensor aging or overloading.

solid torque sensor for motor testing

Picked up this rotary torque sensor to check torque on a rotating motor shaft. The flange setup worked better for me than the usual shaft coupling type. It feels pretty sturdy too. I had to double-check the wiring before powering it up, but after that it was straightforward. No complaints so far.
