TESTING & DEVELOPMENT

TEST & MEASUREMENT PRODUCTS - LapDAQ

LapDAQ is a compact, rugged enclosure designed specifically to house 5B signal-conditioning modules - possibly the most reliable, rugged signal conditioning electronics available. LapDAQ accomodates up to sixteen (16) modules providing protection from industrial or other harsh environments in a highly compact configuration. The LapDAQ system's power supply meets all the power requirements for up to 16 5B modules.

The LapDAQ system’s modular architecture makes this unit an ideal solution for a variety of applications. The system is a rugged, laptop-sized unit that runs off of a battery, 12-volt DC power supply or 110 or 220-volt AC adapter. It is configurable up to 16 channels of variable inputs such as voltage, current, RTDs, thermocouples, strain gauges (including excitation voltages), load cells and pressure transducers; virtually any type of signals for which 5B modules can be utilized. The "plug and run" design allows the user to quickly and simply change the signal conditioning.

Connector "panellettes" further enhance the flexibility of the LapDAQ system. These specially designed plug-in modules provide connectivity for BNC, Lemo, thermocouple mini, and banana-plug connectors; enabling the user to mix and match cable connectors and providing greater reliability, accuracy and durability over wire screw terminals. These user-configurable connector panels allow the use of standard cables and connectors for any sensor.

5B Signal Conditioning Modules

The 5B Series of signal conditioning modules represents a generation of low cost, high performance plug-in signal conditioners. Originally designed for industrial applications, these modules incorporate transformer-based isolation and automated surface mount manufacturing technology. 5B signal conditioning modules provide a single channel of isolated analog input or output, and have compact, economical components whose performance exceeds that available from more expensive devices. Input modules interface with all types of external sensors. The modules filter, isolate, amplify, and convert the input signal to a high-level analog voltage output. The output modules accept a high-level analog voltage signal from a host system, then buffer, isolate, and amplify before providing a process current or voltage output to field devices. Combining 1500 V rms continuous CMV isolation, ±0.05% calibrated accuracy, small size and low cost, the 5B Series is an attractive alternative to expensive signal conditioners and in-house designs.

Roush's LapDAQ is designed specifically to house and support 5B signal conditioning modules. Providing everything from a compact set of custom designed 5B back planes to low noise, built-in power supplies, the LapDAQ offers a superior, portable enclosure for harsh environments. The 5B signal conditioning modules are available for:

- DC Voltage ranging from +/- 10 mV to =/- 40 volts
- Frequency inputs ranging from 500 Hertz to 50 KHertz
- Thermocouples including J, K, T, E, R, S, b, and N
- RTD’s including 2, 3, and 4 wire
- Potentiometer inputs ranging from 100 ohms to 10 Kohms
- Strain gauges both full and half bridge
- Current input 4-20 mA
