Product Description

The OS3 switch is a point level sensor with built-in electronics and works with no moving parts. This level switch is designed to offer industrial supply voltages and outputs that can directly drive higher power loads. This small optical switch detects the presence or absence of almost any fluid type in temperatures up to 125°C.

This industrial optical sensor is capable of driving high power loads and able to sink/source up to 1 amp. The switch is designed for high power signaling of liquid presence/absence of liquid or operation at a high voltage. The OS3 is made from Polysulfone or Trogamid® and features different thread size options and is mounted externally.

This optical level sensor is compact in size, with a lack of moving parts, and features transient over-voltage, short circuit protection, and is extremely accurate for point level detection in high-stress environments. Optical liquid sensors operate accurately in any size tank, and are designed with a very robust construction permitting use in a wide variety of demanding applications. The monitoring and prevention of leaks is critical for service interruptions, to protect equipment and is critical to many industries. Optical sensors can be mounted inside or outside of any tank, ideal for industrial applications because they are compatible with most fluids and chemicals.
