Multi-recorder TMR-300 Series is a compact multi-channel data acquisition system that can combine various measurement units according to the purpose of measurement. Due to its compact size and light weight, the system can be easily installed for measurement not only on existing structures such as machines and bridges in which the installation space is restricted, but also on moving bodies such as automobiles, aircrafts and ships. For the measurement of automobiles, the system is applicable to sensors used for various purposes of tests including traveling performance, maneuverability, ride comfort and safety.Up to ten measurement units for inputting sensors can be connected together and placed in a small space, or each measurement unit can be installed in the vicinity of sensors by connecting the measurement units in series with a control cable. Furthermore, the use of distribution unitallows synchronized measurement of measurement units installed in a wide area.
The control unit is equipped with interfaces for control. Various settings and start/stop of measurement is controlled using the display unit. Control is also possible from a personal computer through USB or LAN interface. The built-in wireless LAN enables operation and monitor display using a tablet PC. (Built-in wireless LAN is not available for overseas model.)
In addition, CAN-GPS unit TMR-351 and IEPE sensor input unit TMR-361 are now under development.
TMR-300 series benefits
- Distributed connection 1
- The cable between the control unit TMR-311 and the measurement unit is extended for installation of measurement units. The distributed connection allows installation of the measurement units in a small space.
- Distributed connection 2
- The distance between two control units can be extended up to 100 meters for synchronized measurement in multi-recorder TMR-300 series.
Measurement is possible for multiple points scattered in remote places (320 points at the maximum using four control units). - Distributed connection 3
- By the use of distribution unit TMR-371, up to ten measurement units can be distributed with extension distance of 100 meters at the maximum between the distribution unit and each measurement unit. Since each measurement unit is placed in the vicinity of sensors, each sensor is connected to the measurement unit using a short cable. This also helps to save labour and cost for sensor cabling.
- Long-time recording possible
- Measured data are recorded directly into a computer by connecting the control unit TMR-311 to the computer using LAN cable. This system is also suited to fatigue test because long-time recording is possible without depending on the capacity of TMR-311 data memory or SD card.
- Control using display unit
- By the connection of display unit TMR-381, stand-alone control of various units is possible including setting, measurement control, monitoring and setting file management.
- Control using a tablet PC
A wireless LAN(*) is built in the TMR-311. It enables operation and monitoring using a tablet PC.(*) Built-in wireless LAN is not available for overseas model.
Control unit TMR-311 |
This works as the central unit of multi-recorder system. It controls, supplies power to and collects data from the connected measurement units. Up to ten measurement units can be controlled for measurement of 80 points at maximum. |
| Display Unit TMR-381 | 
|
By the connection of display unit TMR-381, stand-alone control of multi-recorder becomes possible such as setting of various units, measurement control (balancing / measurement start and stop / automatic measurement setting), monitoring (T-Y sweep / Y-T cont. / X-Y / numerical) and setting file management. When dedicated I/F cable is used for connection, external power source is not required because this unit is operated by the power supply from the control unit TMR-311. It is also possible to use a LAN cable for connection. In this case, extension is possible up to 100 meters and a USB mobile battery can be used as the power source. |
