Pulsar supplied Level Star non-contacting ultrasonic level measurement to Croft quarry in Leicestershire to control
stone level in choke-fed tertiary crushers
The Level Star provides relay closures to control the automatic feed to the crusher, maintaining the optimum level in
the crusher bowl to maximise production efficiency and consistency of stone size.
The combination of Level Star and dB3 transducer is robust, reliable and cost-effective and copes well with the high
levels of acoustic and electrical noise present on the plant.
