The Separated Liquid Flow Sensor A1MF can be used to detect high and low water levels, etc., and give a signal when the water level reaches a certain position.
The Non contact Infrared Level Sensor is a device used to sense the level of liquid in a tank. There is a board in the plastic housing. When the liquid level rises, it drives the prism, level switch will output low voltage signal. When the liquid level falls, infrared level control will output high voltage signal.
The photoelectric liquid level switch uses the principle of optical reflection to measure, the performance of level sensor will be affected when it is exposed to direct sunlight or other infrared interference.
Adjust the mounting angle or use a hood to avoid it.
The photoelectric liquid level switch has high precision, low price, high reliability and wide application environment, it is less affected by strong acid, alkali and viscosity.
The reliability of liquid tank level sensor FS-IR2016D is high. It is not affected by liquid corrosiveness, pressure, magnetism, temperature, etc., it is less affected by external factors and has strong stability. EPT sensor is a manufacturer of liquid level sensors with 16 years of experience. We can provide corresponding solutions for all kinds of electrical equipment and other scenarios that require liquid level detection. If your steam microwave oven needs water level control, please contact us, we can provide you with food grade, hygienic, high precision, high reliability liquid level sensor to solve problems such as scale and water wall hanging.
FS-IR2016D optical water level sensor has no mechanical moving components and with high reliability. This hot selling product is small in size and low in cost. Its advantage is high liquid level control precision. And it can be installed from any direction. Its waterproofing standard is IP68. The sensor itself also satisfies RoHS requirements.
FS-IR02B series Water Liquid Single Point Level Sensor, the theory is infrared, it can totally replace traditional float level switch, it controls the level though output high or low voltage. When the detected level is in air, due to reflect of the prism,most of light will enter receiver LED, optical level sensor will output high voltage. When the detected level is in water, due to refraction of the liquid, just less of light enter receiver LED, optical level sensor will output low voltage.
The FS-IR2003D is a single point liquid level switch that can operate in high pressure, high temperature, and aggressive
environments due to its stainless steel and glass construction. This level switch offers industrial supply voltages and outputs that can directly drive loads. This model has a wide operating voltage, which is from 5VDC to 24VDC. The output ways have two types, NPN and PNP. The sensor can detect the presence or absence of almost any liquid, and can be configured to output a high or low signal in either a wet or dry state.
The microcontroller based Stainless Glass Range liquid level switches are solid state, incorporating an infra-red LED and
phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infrared light escapes making the output change state. The sensor can detect the presence or absence of almost any liquid type; oil or water based. It is insensitive to ambient light and is not affected by foam when in air or by small bubbles when in liquid.

VIII Thermistor
Thermistors are a type of resistor that acts as a temperature-sensing element, generally made of ceramic or polymer. Thermistors exhibit a large change in resistance proportional to a small change in temperature.
Thermistors come in two common types:
NTC (Negative Temperature Coefficient) thermistors In these thermistors resistance decreases as temperature rises. An NTC is commonly used as a temperature sensor, or in series with a circuit as an inrush current limiter.
PTC (Positive Temperature Coefficient) thermistors â?? In these thermistors resistance increases as temperature rises. PTC thermistors are commonly installed in series with a circuit, and used to protect against overcurrent conditions, as resettable fuses.
