Pulse Oximeter Repair Solution | Pulse Oximeter Assembly | What inside Oximeter?

Pulse Oximeter

A pulse oximeter is a device that is usually placed on the fingertip. It uses light rays to estimate the oxygen saturation and pulse rate of the blood. Oxygen saturation provides information about the amount of oxygen in the blood. A pulse oximeter can estimate the amount of oxygen in the blood without taking a blood sample.

Pulse Oximeter Repair Solution

If your pulse oximeter is not working properly, try inserting your finger again and keeping your finger pressed on the device, keeping your finger still while reading. Take another reading to get the correct results. See below for details on how to properly insert your finger into the pulse oximeter.

What to do if the oximeter is not working?

• If your pulse oximeter is not displayed then check Batteries are placed in a proper manner like polarities.
• Check the pulse oximeter probes and SPO2 sensor cables.
• In most cases SMD on-off button failure because of frequently used in that case you need to change it.
• Oxygen levels fluctuate and home pulse ox monitors may lose connection or momentarily read incorrectly.

Which Sensor is used in Pulse Oximeter?

All pulse oximeters use red and infrared light to measure SpO₂ levels. Nonin PureLight sensor technology uses high-quality LEDs and a calibrated receptor to eliminate interference from secondary frequencies.

Solenoid Switch Working Principle | Types of Solenoid Switch and its Applications Price

What is a Solenoid Switch

The Solenoid Switch is a type of switch that functions using the principle of electromagnetic induction. When current flows through a coil of wire, it creates a magnetic field within the coil. When the current is turned off, the magnetic field created by the current continues to exist. This causes the solenoid to continue to respond to the signals being sent by the circuit board, producing a series of clicks as current flows through the coil.

A solenoid Switch is an Electrical Switch is used in high power circuits for switching purposes by using a small control signal. The high current circuits are starter motor circuits operated by a small current switch, this switch is mainly operated by extensive logic circuits and it is economically integrated chips and small electronic components. In this article, I discussed Solenoid Switch and its applications.

Solenoid Switch Definition

An electrical switch that is widely used in high current circuits like motor starter circuits comes into action with help of small power switching is called a Solenoid Switch. This switch turns ON a durable switch to connect the battery of a vehicle to the motor’s starter. Once the ignition key is activated then a solenoid switch connects the drive pinion starter. The main features of solenoid switches are high performance, reliability, and durability.

Purpose of Solenoid Switch

A solenoid switch is used to control high-power circuits with the help of small electrical control signals to activate the switch. It also allows the high-power conversion device to be limited to a remote area. These switches are commonly used in automotive engine starting systems.

The Solenoid Switch allows users to turn off the light at a specific location. This is useful for turning off a light in a specific room, or for turning off a light when a person is not present. The light remains on for a short amount of time after the person has left the room, and then turns off on its own.

DC to DC converter +12V to +/-20V Circuit | Applications of DC to DC Converter

DC to DC converter

The DC to DC power supply converts the DC power coming from your wall outlet into a higher voltage that can be used to power electronic devices. The power output of a DC to DC converter is a constant voltage, meaning the voltage is the same regardless of how much current is being drawn. This prevents the power converter from being a risk for overloading, which is important when powering devices that can draw a large amount of current, like computers and electric drills. DC to DC converters usually has multiple output voltages, allowing you to choose the voltage that is best for your application.

DC to DC Converter circuit used to be a converted voltage DC to DC with different concepts. DC to DC converter circuit +12 V to + /-20V is working to change the battery voltage from 12V DC to 20V DC voltage

3000W Stereo Power Amplifier Circuit Diagram using with Transistors

3000W Stereo Power Amplifier

This power amplifier circuit uses a transistor amplifier from the front, signal splitter, driver, and power amplifier. The current consumption required is quite a large power amplifier that is 15-20 A 1500W power amplifier circuits for this. The supply voltage needed by the power of this amplifier is the optimal working order symmetrical 130VDC.

 

3000W Stereo Power Amplifier Circuit

The power amplifier circuit has a power output of up to 1500W RMS power amplifier circuit is often used to power sound systems for outdoor, power amplifier 1500W is equipped to control a DC Offset function to set the power amplifier is turned on at the moment and with no input signal then the output should be 0VDC. They are also equipped with a flow regulator to the power amplifier bias.

In the above series of power amplifiers, 1500W is equipped to control a DC Offset function to set the power amplifier is turned on at the moment and with no input signal then the output should be 0V DC. Then also equipped with a flow regulator to the power amplifier bias. The final part of this power amplifier requires adequate cooling to absorb the heat generated. The power amplifier is not equipped with a speaker protector, therefore it is necessary to diapason protector on the speaker output so that when the power amplifier is not the case turned on the beat to the speaker can damage the speaker.
