The pioneer of qj36 dual-purpose DC bridge strength

The qj36 dual-purpose DC bridge is a precision electrical measuring instrument. The qj36 dual-purpose DC bridge is used to measure the conductor resistance. The precision level is 0.02. The qj36 dual-purpose DC bridge adopts different linking methods to form a single bridge. And double bridge two kinds of measurement circuit. The qj36 dual-purpose DC bridge can measure DC resistance in the range of 0.000001Ω~1000000Ω, measure resistance value of metal materials, contact resistance of electrical equipment such as switches and relays, and DC resistance of motor and transformer windings.

1. The qj36 dual-purpose DC bridge has an accuracy class of 0.02.

2. The qj36 dual-purpose DC bridge measurement range is as follows:

Single Bridge: 102 to 106 Ω Double Bridge: 10-6 to 102 Ω

3. The cold check terminals of the bridge resistance of the qj36 dual-purpose DC bridge are as follows:

R1: PN1 to RX single (right); R2: PN2 to external galvanometer (right);

RM: PX1 to external galvanometer (right); R'M: PX2 to RX single (right);

4. According to the above paragraph 3, this instrument can also be used as a precision grade variable resistance box.

Second, qj36 dual-use DC bridge technical data The qj36 dual-purpose DC bridge can be used in an environment where the ambient air temperature is 20±8°C, relative humidity is ≤80%, and the air contains no harmful impurities.

2. When the temperature is 20±5°C and the relative humidity is less than or equal to 80%, the qj36 dual-purpose DC bridge adopts the voltage and the resistance of each bridge arm according to the rules of use.

Accuracy: 0.02%

Qj36 dual-purpose DC bridge set requirements (user self-provisioned):

1.AC15/2 or AC15/4 galvanometer 2.AC24 amplifier 3.BZ3 standard resistance -0.001 ohm

4.FB871A DC precision power supply (10A, 30V + reversing switch, special wire)

Machining Steel is the use of CNC machining out,and the machining services including drilling, boring, cutting,meatl bending/metal bending, machining Steel Product material: carbon steel, 20#, 45#, A3, Q235,35Cr2MnMo and other series. In the high-speed machining out of the workpiece has a good finish. But machining Steel of the workpiece is easy to rust, so it will do heat treatment, surface nickel plating, chromium plating, surface black heat treatment, etc.. We have a special inspection department to carry out inspection, ensure the material aging hardness and each size to meet the requirements of the drawings, including the Machining Steel Parts application in various industries: automotive, marine, communications, medical equipment, industrial automation equipment.Except them,we supply the sheet metal operations.
