Digital Torque Meter
TQ-5300

The TQ-5300 calculation display can be used in combination with a flange-type high-rigidity detector to convert the detector's pulse output into digital torque values and analog voltage outputs.

The digital output offers three types of digital interfaces (optional). In addition to the conventional RS-232C digital interface, it now includes EtherCAT and CAN, enabling faster digital communication.
By using this digital interface, it has become possible to output the high-precision torque measurement values inherent to the torque detector directly.

The analog output adopts a periodic calculation method that converts for each cycle of the pulse, allowing for high-speed response. It comes standard with convenient remote I/O functions, communication functions, and interlock functions for system upgrades.

Additionally, it supports multi-range measurement functions (optional), allowing multiple torque capacities to be set with a single torque detector.

Features

3 types of digital output

High-precision output of torque measurement values.

By using digital output, it is possible to output torque values with the inherent accuracy of the torque detector.

  • High-precision output of torque measurement values.
EtherCAT

Digital Interface (Optional)

EtherCAT (TQ-0535)
CAN (TQ-0533)
RS-232C (TQ-0532)

Supports multi-range measurement functions.

When measuring different torque capacities, it was necessary to replace the torque detector according to the torque capacity. However, by using the optional multi-range feature (TQ-0536), multiple torque capacities can be set with a single torque detector without the need for replacement. By pre-entering information such as the factor and capacity of the torque detector, switching between ranges can be done easily.

  • Different torque capacity settings allow for a maximum of three range settings.

  • Can be switched from the menu or external mode.

  • In the case of switching ranges from external mode, the current range can be confirmed through the set range confirmation output, which helps prevent measurement errors.

  • Supports multi-range measurement functions.

* When using a multi-range specification, there are conditions based on the torque range being used, so a consultation before placing an order is necessary.

High-speed response with analog output.

The flange-type high-rigidity torque detector changes the signal output frequency from the detector according to the detected torque amount. The torque calculation display calculates the frequency corresponding to the detected torque amount every cycle and outputs it as an analog signal with a fast response.
The fast response analog output follows the rapidly fluctuating transient torque, enabling more optimal control.

  • High-speed response with analog output.

Compatible with the TQ-1000 series.

TQ-1000 Series (Standard Rotation Specification)

Can be connected with the TQ series flange-type high rigidity torque detector.

equipped with analog output for rotational speed

equipped with analog output for rotational speed

Torque and rotational speed values can be output simultaneously in analog form.
By using the option (TQ-0531), torque 2 ch output is possible. For example, when you want to differentiate between control and recording outputs, it can be output from a single computing display.

When the torque value exceeds the set threshold, it is considered abnormal and can output a contact signal, functioning as an interlock. There are a total of three outputs: two channels can be freely set, and one channel outputs when the torque exceeds a maximum value of 110%. The two freely set channels can also be assigned to rotational output.

Case Studies

engine test bench

We provide data to faithfully reproduce virtual loads in the engine bench. By using the TQ-5300 equipped with a digital interface, it is possible to obtain high-precision and high-response torque data.

transmission testing device

From durability tests to efficiency tests, a single torque detector can measure using a multi-range function. Since there is no need to install a detector that matches the torque value depending on the test content, stable measurements can be achieved without changing the conditions.
