Beschreibung
Zusammenfassung:	Programmable apparatus for monitoring an industrial installation, such as for measuring the depth of material in bins or silos, utilizes a computer having a hermetically sealed case (60), with an externally visible display (38) and necessary connections to the installation being monitored. The computer includes non-volatile random access memory (10) for the storage of operating parameters which is written to under control of a portable external programming unit (58) which can temporarily access the computer via an infrared or equivalent communications link (2, 4). The case (60) of the computer has provision (74) for temporary docking of the programming unit, which has a keypad (54) for the selection of calibration and diagnostic routines, and the entry of data or commands to be transmitted to the computer.
