SETTING THE ST ANDARD FOR DRY BLOCK CALIBRATORS

Druck, a leading manufacturer of portable and workshop
calibrators, has redefined the term “temperature calibrator”
with the introduction of the DBC series. This innovative
calibrator combines a highly stable temperature source with
precision measurement of temperature probe signals,
providing a truly stand-alone temperature calibrator suitable for
laboratory, workshop and portable use.

The product range includes Temperature Source (TS) and
Temperature Calibrator (TC) versions. Each version is available
with a choice of two temperature ranges for use up to 150 C
(DBC 150) or alternatively 650 C (DBC 650).

Druck control technology insures rapid settling time, excellent
set-point stability and high accuracy. For improved
measurement uncertainty, a traceable Pt 100 reference probe
can be positioned directly into the well insert. The probe
output is measured and displayed by the DBC.

The TC version is a complete calibration system which
simultaneously controls the reference temperature while
measuring the device under test. In addition, loop power is
provided for transmitters. In calibration mode the percentage
error or temperature deviation is displayed together with the
input and output readings.

DBC Series - key featu res

Ranges: DBC 150: -45° (below ambient) to 150 C.

DBC 650: 50° to 650 C.
Fast response: Rapid heating, cooling and settling.
Stability: Druck control technology provides

excellent temperature stability.
Reference probe: Pt 100 reference probe input.
RS 232 interface: Allows fully automated PC control.
Switch test: Open/closed detection with hysteresis

displayed.
Ramp, preset, step: Programmable Ramp, Preset recall and

calibration Step sequences.
Reduction Inserts: A wide range of standard interchangeable

inserts are available. Inserts can also

be supplied to specific requirements.
Easy to use: Full numeric k e ypad and input/output menu.

TC version - additional features

The calibrator version includes the following features in
addition to those listed above:

Electrical Inputs: Measures RTD’s, T/C’s, mV/V, mA and

ohms.
Dual Readout: Simultaneous reading of source

temperature and device output.
Error Analysis: Percentage error and deviation

calculations.
Loop Power: 24 Vdc supply.

The DBC series are rugged, easy to use and designed to give
years of reliable service. Stand alone operation eliminates the
need for secondary equipment, making the DBC one of the
most cost-effective temperature calibration systems available.
