Yes. A Micro-D connector with color-coded wire pigtail is provided and is designed to complete the run to a DAQ.
The spring force on standard units is 0.2 newtons/mm or 1 pound/inch.
Yes. A comparison chart may be found at: http://files.microstrain.com/Displacement-Sensors-Comparison.pdf
Sandard DVRTs can operate up to 100 PSI. However, custom-designed sensors have been used in applications up to 10,000 PSI. Please contact your sales or support engineer for more info.
Typically, every DVRT is calibrated at the factory with its accompanying DEMOD signal conditioner. The calibration is made over the entire system (DVRT and DEMOD) to insure the highest accuracy. DVRTs and DEMODS are color-coded to insure that they stay together as a pair when in use.

| DEMOD Type | Temperature Compensation |
|---|---|
| DEMOD-DVRT | No |
| DEMOD-DVRT-TC | Yes |
| DEMOD-DC | No |
No. LORD MicroStrain® makes a DEMOD-DC which provides an alternate method of DVRT signal conditioning. The DEMOD-DC provides conditioning as an in-line connector and connects to your DAQ. Although not normally recommended, a DEMOD-DVRT or a DEMOD-DVRT-TC can be used without its Motherboard enclosure; external power is the only requirement.
The term ‘Motherboard’ refers to the LORD MicroStrain® DEMOD-DVRT or DEMOD-DVRT-TC signal conditioner mounting chassis. The standard Motherboard provides a mounting slot and power to the individual DEMODs. The Smart Motherboard provides a mounting slot, power and digital communications (RS-232) to the individual DEMODs. Both Motherboard and Smart Motherboard provide analog ouput to a DAQ. In addition, Smart Motherboard provides digital output to a computer. Motherboards and Smart motherboards can accommodate 1 to 8 DEMOD cards.
