ANALOGUE RECORDING MODULE (ARM).
* Data Acquisition / Logging Module
* Rugged & Compact
* Modified & Custom Designs
The Astech ARM is a self-contained unit which records transducer
or sensor data and is small enough to install at the actual measurement
location. Analogue signals connected to it are stored in memory at
selectable sample rates which can range from 10,000 per second
to one every 30 minutes, making the ARM suitable for dynamic or
slowly changing data - or a combination of both since fast and slow
channel sample rates can be mixed. A memory capacity of 262,000
measurements (524,000 with the non-IR version) provide a useful
recording time period, even at fast sample rates.
A high speed bi-directional infra-red link is used for communication
between the ARM and laptop/PC, eliminating cabling and the need
to make any physical connection. Valid operation of the link is
indicated by LEDs on the infra-red transceiver interface unit and the
Alternatively a direct RS232 connection is available.
The infra-red communications link provides important advantages and
* Cable-free input of setup data and downloading of stored
measurements - especially useful when the ARM is installed at
* Up to 2 Metre isolation enables measurements from high-voltage
and other hazardous areas.
* Remote start/stop of recording and resetting using handheld
* Measurements can be transmitted through sealed glass
enclosures and fluids.
An important feature of the ARM is the ability to survive and function
under hostile operating conditions. Suitability for a wide range of
measurement environments is ensured by providing a choice of two
types of housing - a lightweight ABS enclosure or an IP67 sealable
A recent application was a custom design ARM for the measurement
of strain and temperature on a conveyor belt whilst passing through a
refrigerated section at -60°C. Internal heaters ensure that the battery
is maintained within its working temperature range.
