A sensor is a device that detects to some type of event or change in its environment, and responds by reporting or sending that information to an operator or another device.

The input detected by the sensor can be just about any environmental stimuli, including light, heat, motion, moisture, pressure, and more. The sensor detects and measures the change, and transmits that data through some output signal. A sensor that measures temperature, for example, can output that data as voltage signal readable by another device like a display or control component.

Sensors are available in a wide variety of shapes and sizes, with different designs and technologies used to detect specific, individual inputs. Sensitivity and accuracy also vary device to device.

LS-7 Series Image
  • No. 22 AWG
  • RoHS Compliance
  • SPST, 20VA Switch Rating
These low-cost units are ideal for high volume use in small tanks and vessels. Engineered plastics construction offers broad compatibility in water, oils and chemicals.
  • Ideal for Oils and Fuel

RSF80 Series Image
  • Horizontal Float
  • 25 VA Switching Power
  • 0.6 Amp Switching Current
  • NO/NC Contacts
  • External Mounting
The RSF80 series from Cynergy3 is designed for external mounting achieved with a 1/2" NPT taper thread. This avoids the need for access to the inside of the chamber and is ideally suited to applications where space or fitting time are prime considerations. They are manufactured in a variety of materials to suit most commonly used liquids. The switch action may be reversed by rotating the device through 180°. Typical applications are diesel level for generators, hydraulic fluid level, and gearbox oil level.

A/CTA2 Series Image
The 4-20 mA Output Analog Current Sensors are designed for use in any AC current monitoring application in which you are looking to monitor a particular piece of equipment. The "Average" style current sensors should be used in applications where the Sinusoidal waveform has no distortion or noise on the conductor being monitored. Applications may include monitoring a resistive type load such as an incandescent light bulb, heating element as well as any single speed linear load. Note that the "True RMS" sensors are able to be used in all applications since the "True RMS" current sensors provide the best overall accuracy and should be used in applications which includes Variable Frequency Drives, Switching Power Supplies, Computers and Data Centers, Electronic Ballasts, SCR's, and Variable Speed Loads. For currents monitored above 250 Amps, the CTA2-5 and SCTA2-5 are ideal for use with a step down Ratio:5A Output CT (Current Transformer) in stepping down current in a monitored conductor to a proportional 0 to 5A output signal. The current sensors are available in both solid and split-core versions which also includes a Patented (Pat. No. US 7,416,421) 35 mm Din Rail mounting foot for easy installation in panel mount applications. The solid-core versions are a great choice for new installations or OEM applications in which cost sensitivity, lower trip points and environmental issues like dust and moisture may be of concern. The split-core version of the current sensors work great in retrofit applications and for use on service technicians vehicles since one or two parts will work in most applications and can be easily installed without disconnecting any wires.
