The RDR Remote Inclinometer Package is an extension of their RDI series of digital inclinometers. The RDR is supplied as a calibrated set featuring an environmentally sealed measurement sensor package, a separate LCD display box, and the interconnecting cable. All of the standard RDI features have been incorporated into the remote sensing package including single and dual axis measurement, user defined inclination ranges, multiple outputs with any combination of analog output, LCD display, RS232 communication, and up to three open collector switch outputs, as well as optional temperature compensation when additional accuracy is required.

The LCD display can be configured to display degrees, percent grade, or inch per foot rise with either 0.1° or 0.01° resolution. The display model is automatically supplied with green, yellow, and red LEDs set at pre-defined angles within the measurement range providing the operator a visual feedback. For leveling applications, the LED function could be set so that the green LED lights when the device is level, and switches to yellow or directly to red when out of level. They can also be used to indicate safe and unsafe conditions such as to prevent vehicle rollover. The green light can be set to indicate safe operating zones, the yellow light can be a warning zone, and the red light could be a danger zone.

The digital display model also provides relative zero and min/max functions. The relative zero allows the operator to temporarily zero the digital readout to obtain relative slope changes. The operator will always know when the device is in the REL mode by the (*) symbol that is displayed after the angle. The min/max function provides the smallest and largest angle the device has sensed since the last reset. There are three open collector outputs that can be optionally set to switch anywhere within the measurement range and can be configured for either normally open or normally closed operation. The outputs can be used to drive an external buzzer, horn, lamp, solenoid, or relay allowing for audible and/or visual warnings and possible equipment shut down control. The LED's on the front panel display are tied directly to these outputs and are configured to indicate when switching occurs.

The analog output is available as either temperature compensated or non-temperature compensated depending on the required accuracy for the specific application. A 12-bit digital to analog converter is used to perform the conversion. The RS232 output is presented in decimal format in degrees, percent grade, or inch per foot rise. The output is formatted one reading per line for single axis units and two readings per line for dual axis units. The first reading for a dual axis unit represents channel 1 (normally side to side) and the second reading represents channel 2 (normally fore and aft).

Multiple mounting configurations are available including dual axis units with both channels reading the same direction for redundancy in safety applications.
