High Voltage Thermal Converters
Product Information
Each high voltage thermal converter is manufactured in a copper alloy high polished chrome plated housing tube for highest surface reflection and adjusted for the best AC-DC difference and so that a constant impedance is held through the entire frequency range. Each unit can be supplied with BNC, N, or GR874 input connectors.
Measure Tech uses a fully automated calibration system, EL-2400, which was manufactured for Air Force precision measurements laboratories. The calibration is performed by comparing our product to a calibrated standard traceable to NIST.
In addition, for all thermal converters a 4' long low noise cable (model number EL-2000) is available with excellent shielding capabilities. This product mates with all of Measure Tech's thermal converters as well as any other thermal converter with an output connector of MS3102A-10SL-3P.
Benefits
The high voltage thermal converters are manufactured with vacuum thermocouples with a maximum DC reversal error of 0.02%. In addition, a DC reversal error of 0.005% is available upon request.
