Description

There are three types of torque sensors used in mud logging system, mechanical torque sensroe, electromagnetic sensor or TDS torque sensor. A mehcanical torque sensor is a pressure transmitter actuall; the working priciple is same to the principle introduced in paragraph 4.3.1. In WELLSTAR, wiring points are assigned on junction box 1 for a mechanical r and an electromagnetic torque sensor with *4V power supply, and wiring points are assigned on junction box 4 for a TDS torque sensor without power supply.

Principle:

Base on the "Hall Effect", a bypass circuit can be adopted to measure the armature current directly. This by measuring the current through to an electrical motor for rotary table with a bypass circuit, the variations of the string torque corresponding to the current variations can be measured indirectly. Here a electromagnetic torque sensor provides a bypass circuit once powered.

Specification:

* Measuring Scope: *****0A
* Responding frequency: ******0HZ (AC/DC)
* Accuracy: Accuracy: =1%FS (*5 ?)
* Workable temprature: **5 ?**0 ?
* Signal Output: ***0 mA
* Power Supply: **4VDC
* Max. current: =*0mA
* Load resistivity: <**0O Load
