operation eliminates the need for secondary equipment, making the DBC one of the most cost-

effective temperature calibration systems available.

Applications

MULTIFUNCTION DRYBLOCK CALIBRATORS

The DBC series comprises of two models, the DBC TS Temperature Source and the stand alone DBC TC

Temperature Calibrator. They are designed for calibrating and maintaining temperature elements,

probes, transmitters and thermostats. The two models share the same temperature control technology

and differ only in electrical measurement capabilities.

DBC TS Temperature Source

The DBC TS temperature source uses an internal high accuracy sensor to measure the equalization block

temperature. Alternatively, for direct measurement of the insert temperature, a PT 100 electrical input

is provided. Traceable reference probes are available. A switch detection input is supported with a fully

automatic switch test facility.

DBC TC Temperature Calibrator

The DBC TC temperature calibrator adds electrical measurement capabilities for RTD’s, thermocouples,

mA, mV/V and ohms. 24V loop power is also provided. The dual parameter display is quickly configured

from the input/output menu to read the reference temperature, the device output and the error. This is

a self-contained temperature calibration system for stand-alone operation.

Calibrating RTD Sensors and Thermocouple Sensors

With conventional dryblock calibrators, ancillary indicators are usually required to measure sensor outputs.

The DBC TC temperature calibrator and measure 5 types of RTD and 11 types of thermocouple. It

supports 2, 3, and 4 wire RTD configurations and provides automatic cold junction compensation for

thermocouples.

Preset temperatures can be programmed to standard test points for quick recall when required.
