1 INTRODUCTION

The DBC series of temperature calibrators test and calibrate temperature devices. The series comprises two types: a TS (Temperature Source) and a TC (Temperature Calibrator). Multilingual firmware provides a menu-driven user interface in English, French, German, Italian, Spanish and Portuguese. An RS232 digital interface, supplied as standard, enables remote operation of the instrument from a compatible computer.

TS (Temperature Source)

The DBC-TS generates stable temperatures and accurately measures the temperature of the dry well. It provides an automatic switch test facility.

There are two models of the DBC-TS, providing the same operating capabilities at different temperature ranges:

DBC 150-TS : -45°C below ambient temperature to +150°C.

DBC 650-TS : +50°C to +650°C.

This series of calibrators uses the GE technology temperature controller, providing high performance temperature stability and accuracy. Temperature generation can be controlled either in manual mode (direct) or automatic with ramping, stepping or preset functions. The dry well temperature can be measured either with the internal probe or with an external certified reference probe. The key-pad, display and electrical connections enable the user to carry out test procedures for RTD and thermal switches with a hysteresis calculation.

TC (Temperature Calibrator)

The DBC-TC generates stable temperatures and accurately measures the temperature of the dry well. It measures process signals from the temperature devices under test.

There are two models of this series, providing the same operating capabilities at different temperature ranges:

DBC 150-TC : -45°C below ambient temperature to +150°C.

DBC 650-TC : +50°C to +650°C.

This series of calibrators uses the GE technology temperature controller, providing high performance temperature stability and accuracy. Temperature generation can be controlled either in manual mode (direct) or automatic with ramping, stepping or preset functions. The dry well temperature can be measured either with the internal probe or with an external certified reference probe.

The key-pad, display and electrical connections enable the user to carry out test procedures for thermocouples, RTD, switches, temperature transmitters and converters, regulators. Both TC models contain a switch test function with a hysteresis calculation. This Input/Measure facility enables direct connection and reading of thermocouples, RTD, Voltages, Current and Resistance: the dual display can simultaneously show the generated temperature (with internal or external
