Frequently Asked Questions About Liquid Level Sensors
Q: What is a liquid level sensor?
Liquid level sensors are used to determine if a liquid exists at a particular level in a container. They are designed to change state when a liquid level changes.
Q: Why are level sensors important?
A sensor is able to detect a change in liquid levels and communicate that change to the user. Having knowledge of the position of the liquid is critical in applications such as running out of oil or fuel.
Q: How does a liquid level sensor work?
GTS stock three different types of liquid level sensors used to detect the point level of a liquid; Capacitance, reed switch and hydrostatic level sensors.
Q: What is a capacitance level sensor?
Capacitance level sensors (TLL150, TLL130, TLL171 and TLL352) are operated by two parallel metal plates that act as a probe and form an electrical circuit when submerged in a liquid. If the liquid level rises and falls, this will change the capacitance measured by the probe in a predictable way, and therefore it can be used very effectively as a measurement of liquid level.
Q: What is a reed switch level sensor?
Liquid level sensors with a reed switch(S3 and S5 senders) use a magnetic float that adjusts with the liquid surface. As the magnetic float moves, the switch opens or closes, giving an electrical circuit to operate the sensor.
