The T7 is a solid state absolute inclinometer that senses tilt angles over a full 360° range in a single axis. The T7 is sealed against dust (IP68 rated) for operation in dirty environments. The T7 incorporates a number of breakthroughs to create a new type of inclinometer that is rugged, compact, fast, flexible and easy to use.
The T7 is available in several interface and protocol options. The physical interface can be RS232, RS485 or US Digital's CAN (Controller Area Network). The protocol can be either US Digital's serial protocol or Modbus RTU. The RS232 version supports a single T7 with up to 100 ft of cable. For users that need longer cable lengths or multiple T7s on a single bus, the RS485 or US Digital CAN (Controller Area Network) version can be used. The USD-CAN protocol allows a network of up to sixty-four T7s to be connected to a single host. Power for each T7 is supplied over the CAN network cable. The host accesses the USD-CAN T7s through US Digital's low cost CANA-232/CANA-485 adapter module. This module allows the host to access each T7 on the network using simple, easy serial port commands, just like the RS232 version. The RS485 version supports up to 32 T7s on the bus.
The Modbus RTU version is suitable for users that require an industry standard, open protocol. The host may access each T7 on the bus using standard Modbus read/write register function codes.
The T7 calculates tilt angle (inclination) by sensing the acceleration from solid state accelerometers integrated into a monolithic chip. Gravity, centrifugal forces, and linear speed changes are all forms of acceleration. The T7 will report the mathematically calculated tilt angle based on all sensed acceleration(s).
