 The 24ZM series of encoders can maintain a resolution of 1mm over a level range in excess of 4m. The sliding contact design allows the encoder to be un-powered either deliberately or through a power supply interruption without losing its datum information.
The 24ZM series of absolute multi-turn 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.
The 24ZM series can be supplied in the following formats:
12bit : Resolution 1mm : Measurement range 4096mm
10bit : Resolution 1mm : Measurement range 1024mm
All necessary associated hardware can be supplied including:
Pulley
Mounting Bracket
Float
Counterweight
Connecting cable etc.
Full details of how to interface the encoder for telemetry and data logging purposes are also available.
