Safe Load Indicators

The Sentinel Instruments D9000 Safe Load Indicator has outstanding performance, accuracy, with reliability and ease of calibration coupled with easy to perform self diagnostic routines.

Each load cell (and angle transducer) has its own smart amplifier where the sensor outputs are converted to digital signals and each amplifier has its own address.

The CPU is then only required to act as a digital data polling station and thus has a large capacity to process load charts, sea state conditions, diagnostic routines and memory for data logging The CPU outputs the data to the various displays, alarms and cut-out devices necessary for the safe operation of the crane.
The display is laid out in an ergonomically manner to allow the user easy reading of all displayed data whilst a two line LCD display enunciates the status of the system including current POL and Sea State selections and any error messages.
The Sentinel Instruments Safe Load Indicator is easy to install, maintain and calibrate, is reliable in service and has a 1000 Lift memory.
