The ES-PPO1 is a sensor that converts the rotation of the counter into a two-phase signal.
It is compatible with the PPO-25, PPO-40 counters. ES-PPO1 is installed between the PPO counter itself and the meter pointer indicator, and is fastened with elongated bolts.
The rotation of the PPO counter shaft is transmitted to ES-PPO1 via a cam clutch. Inside the ES-PPO1, there is a disk with slots on the shaft. Optocouplers are located against the slots. Next, the signal from the optocoupler is amplified and transmitted to the output. The number of generated pulses from the optocoupler is proportional to the number of revolutions of the counter shaft. 50 pulses are generated per rotation of the axis. Pulse counting is performed using an external reporting device. Pulse counting allows you to determine how much the counter shaft has rotated relative to the initial position. Thus, an external counting device allows you to determine and dose the amount of pumped fuel.
The advantage of ES-PPO1 over competitors:
- less backlash and smoother rotation compared to the OSS
- lower price for good accuracy
- there is no need to make changes to the counter as from UP to 10
- detachable ES-PPO1 connection with a wire, which facilitates installation and maintenance
- simple installation similar to OSS sensors
- tightness and resistance to fuel
- the wire is protected by a corrugated pipe
- protection against reverse polarity of the power supply
- protection of output signals
