73-A Acceleration Monitor

73-A Monitor

The 73-A, acceleration monitoring system, can measure the acceleration of a component. When acceleration exceeds a preset value, an alarm can be triggered.

Features

Small size (96 x 48 x 132mm, 450g)
Easy installation into control panels (DIN standard 92 x 45mm rectangular opening)
There are two types of monitors, 73-A2 for use with a separate charge amplifier, and 73-A3 for use with accelerometers with a built-in amplifier
Cable between monitor and transducer can be several hundred meters long
Parameter settings (output scaling value, zero setting, peak value and bottom value hold, alarm delay time setting, alarm point resetting, etc.) are easily made at the front panel. Panel cover prevents accidental tampering with the settings.
The monitor determines whether or not the sensor operating conditions and installation position are correct.
Built-in power supply for charge amp or accelerometers
Free power supply (AC85-264V, 50/60Hz)
Several signal filters are included, and custom filters can be specified by the user.
A centralized control system using a personal computer can easily be constructed using these monitors due to their output of 4-20mA or RS-485 communications interface.
