Michigan Scientific Series M460 Digital Telemetry System is a multi-channel transmitter designed to relay one to eight channels of strain gage bridges or thermocouple based transducer measurements. This system offers 16-bit resolution, simultaneous sampling of all channels, fully differential amplifiers for high common mode rejection, and anti-aliasing filters prior to digitization. Each individual strain gage driver features its own gain and shunt resistor values making system configuration flexible.
The system’s multi-channel receiver is designed with RF diversity and error checking to prevent data loss and corruption due to reflections or shadowed transmissions from the transmitter. Output data is provided as high-level +/-10V analog on a rear connector for direct interface with most data acquisition systems, or the data can be captured in digital format for immediate display and collection via an Ethernet port to a PC. Analog output options include additional choices for data cutoff frequencies and adjustment of zero offset. Indication of transmitter and receiver status is provided by LED indicators on the receiver’s front panel as well as analog output signals that can be monitored for quality of transmission, low power conditions, and shunt status at the transmitter.
Typical applications include measurements on rotating equipment and in situations where access by a wired sensor is not possible. The system’s hardened design is intended for operation in hostile environments where vibration, extreme temperatures, high accelerations and contaminates are present. These features ensure successful data measurements using our newest technology.
