Torque sensor WDH Dynamic Torque Measurement

Product Name: Dynamic torque sensor Standard Model: WDH-B1 (standard Universal)) Brand: WDH (Ward) Unit: Taiwan First, the principle: the use of Germany's most advanced non-contact strain measurement principle of the sensor signal output technology and energy into are using non-contact transfer mode; the sensor in measuring positive, reverse torque, without the need for commutation and zero set the sensor signal output using a variety of ways (frequency, voltage, current) sensor signal output, adjusted directly into the PLC acquisition system speed measurement: Speed ??is measured using rotary encoders, photoelectric chainring way; photoelectric chainring way high-speed measurements at low speed using a rotary encoder measurement, but also for angle measurement Second, the technical characteristics: signal and power supply It is non-contact transfer, without slip rings or brushes; no change to zero and can measure positive and negative torque; the signal with a frequency output, high signal to noise ratio, good anti-jamming; fast response can be measured start moment, more measurable transient torque; from high and low speed limits, can accurately measure the real-time torque and power; the linearity of the sensor repeatability, high reliability; sensor compact, small size, light weight torque is not accuracy of 0.1 ~ 0.5% FS repeatability of 0.1 ~ 0.5% FS linearity 0.1 ~ 0.5% FS hysteresis 0.1 ~ 0.5% FS Overload ≤150% Insulation resistance> 200M Operating temperature range -20 ℃ ~ + 60 ℃ relative humidity <90% RH sensor supply voltage ± 12VDC sensor power <4W load current <15mA sensor output signals: 1, the torque output signal: frequency signal output (5K ~ 15KHZ, zero is 10KHZ, forward to 15KHZ, the reverse is 5KHZ, with particular reference to "product factory test report" amplitude of 5V) 2, tachometer output signal: output frequency signal, the amplitude of 5V, depending on the number of pulses per revolution gear speed sensor or the encoder disk teeth 3, the sensor signal selection: sensor output amplitude of the signal can be raised to 24V, direct supply PLC acquisition and processing, the frequency of the signal sensor output F / V, F / I is converted to an analog signal: voltage signal output (± 5V, ± 10V, 0 ~ 5V, 0-10V optional) optional current signal output (4 ~ 20mA) Optional Note: positive and negative torque sensor OK: The sensor is fixed at one end of the output shaft, a clockwise torque is applied to the other end, to determine this is positive, and vice versa for reverse.
