Description
The T7 is now IP68 rated. For more details, download the T7 IP68 Certification.
The T7 is a solid state absolute inclinometer that senses tilt angles over a full
360
range in a single axis. A multi-axis version is planned for the future. 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).
The serial port interface provides an efficient way to read and write data to a
network of T7s. All configurations and parameters are stored in nonvolatile
memory. A Windows demo application is provided for displaying the angles and
temperature as well as setting operating modes, orientation, zero position,
damping / averaging time, direction, and more for every T7 on the network. In
addition, a Windows DLL gives the user a set of simple functions to read and
write data to a network of T7s.
