1 Introduction The medical injection needle penetration force tester is a production and inspection equipment for medical instruments with mechanical and electrical integration, and is an important product of a pharmaceutical machinery company in Shanghai. It is widely used in manufacturers of medical needles. The machine uses PLC to control the stepping motor to make the medical needle go down to penetrate the film. During the penetration process, the force on the needle is transmitted to PLC through AD conversion through communication through the pressure sensor. The test report is printed through the touch screen printing function. Through data calculation and curve judgment combined with data judgment, the quality parameters of the puncture force of the injection needle product are detected. 2 Solutions 2.1 Project design (1) Initialization of the force sensor: advanced data is transmitted through the force sensor communication

ADSL service uses existing copper wire resources to realize high-speed data, voice and image transmission, which enhances the advantages of traditional operators in data access, but also brings new challenges. Since the transmission rate of ADSL service is higher than that of old ordinary telephones, it puts forward higher requirements for the quality of subscriber lines. The specification, length and quality status of copper wires used in existing user networks are complex. In order to ensure the true implementation of ADSL services, the user wires must be tested first. In this context, Beijing Telecom R&D Center has undertaken the test work of Beijing Telecom subscriber line quality and ADSL service opening rate, and has successively advanced in Wuluju, Clothing Academy and other regions

resistance Tester Basic principle and purchase of 1、 Withstand voltage Tester Withstand voltage Tester Also called electrical insulation strength tester or dielectric strength Tester 。 The test of applying a specified AC or DC high voltage between the live part and the non live part (usually the shell) of the electrical appliance to check the withstand voltage capability of the insulating material of the electrical appliance. During long-term operation, electrical appliances should not only bear the action of rated working voltage, but also bear the action of overvoltage that causes a short time higher than the rated working voltage during operation (the overvoltage value may be several times higher than the rated working voltage value). Under the action of these voltages, the internal structure of electrical insulation materials will change. When the overvoltage intensity reaches a certain

This design idea shows how to create a reliable, low-cost and simple inductance Tester 。 this Tester The basis of this is a Piltz CMOS buffer oscillator (Figure 1). This oscillator uses a single CMOS inverter bias to form a high gain inverting amplifier in its linear region through resistor R1. Because of this high gain, the inverter consumes less power than a non buffered gate, and even a small signal can drive the output to a high or low level. LC π network forms a parallel resonance, and the resonance frequency is fO=1/2 π. This frequency corresponds to the period CS=C1 | | C2=50 nF. So

The circuit adopts the popular and easy to find LM3914 integrated circuit. This IC is a very simple driver, does not need a voltage regulator (it has a built-in regulator), and can be powered from almost every source. This circuit is easy to explain: when the test button is pressed, the voltage of the car battery is sent to the high impedance voltage divider. His goal is to divide 1,25 V (or less, to the lower value) by 12 V. This solution is to set the 12V sampling voltage of the internal regulator to the feed of the internal voltage divider, because it cannot adjust 12V, and the voltage drops to a lower level (the linear regulator can only be removed). Just didn't adjust the wiring, voltage regulator
