With the excitation feature for continuous data-logging, this ultrasonic sensor is designed to provide a non-contact method of level, volume, proximity, distance, presence, and absence detection. With technology to compensate for unpredictable variables such as humidity, temperature, and agitators, the sensor is versatile and flexible.

Recommended for indoor use, the ultrasonic sensor detects difficult targets. Features a versatile range from 6" to 35', this transducer's high sensitivity handles non-reflective and soft surfaces. With built-in technology to compensate for temperature, this sensor is well suited for object detection.

These float switches work like a standard light switch, they open and close contacts to control whether or not signal current can pass through. When they are closed, the current is flowing and when they are open, the current is not flowing. The "normal" state is when the float switch is down, resting on it's cable or float stop. Some float switches have hysteresis built-in which tells the pump not to chatter, but to turn off at one level, and turn on only at another level. The floats have multiple up to four switch points in a single float. Many float switches are simply used for level indication.
