This is a Contact style Encoder used primarily by the water industry. It has the advantage of extremely low power consumption compared to optical styles when used with dataloggers or telemetry systems based in remote locations. It has an 8 bit Gray output which can be scaled using pulley type P256 to correspond to 1mm steps in water level.

Mechanical

The 24ZM series of multi-turn Absolute Contact Encoders can be used to measure water level via a float actuated pulley. A Gray output code of up to 12 bits is generated which allows 1mm measurement resolution over a 4096mm range. As the code is continuously available whether or not the encoder is being powered the water level datum is not altered by random failures in supply voltage. This design also lends itself to a situation where the power needs to be switched off periodically by the user to conserve energy.

Hollow shaft encoders using either conventional optoelectronic technology or Hall Effect magnetic sensors are available.

The HSA-100 Series is based on a 25mm bore size and is designed to withstand temperature ranges from
-46 to +85 Centigrade. It has a high tolerance to shock and vibration making it suitable for a variety of Heavy Duty applications. One variant is currently used in an armoured vehicle control system.
