Electrical Test & Measurement

Source, simulate and verify

Three series and twelve models. A sealed handheld that sources and measures loop signals, and eleven dry block calibrators from −45 °C up to 1210 °C, including a range that reads the sensor under test on its own reference channels. Filter by application, temperature range and measurement capability to narrow it down.

The Range

Three series

One electrical, two temperature. The difference between the two dry block ranges is whether the instrument also reads the sensor you are calibrating.

Electrical1 model

GPS-925

Multifunction Process Calibrator

A handheld that sources and measures voltage, current, millivolts, resistance, frequency, thermocouples and RTDs, so one instrument replaces a current source, a voltage source, a resistance box and a frequency meter on a site visit.

DBC Series

Dry Block Temperature Calibrators

Five dry blocks covering −30 °C to 1200 °C. The block is the reference, so RTDs, thermocouples, thermistors and liquid-in-glass sensors are checked without a stirred bath.

DBC-A Series

Advanced Dry Block Temperature Calibrators

The same dry block with a measurement front end built in. Reference PRT and thermocouple channels, mA, mV, V and resistance measurement and a 24 V loop supply, so the sensor under test is read by the instrument generating the temperature.

Choosing

Four things worth settling first

Start with the temperature range

The range is fixed at manufacture on every dry block, so pick the model that spans your set points with margin at both ends. A DBC-650 cannot be re-blocked to reach 1200 °C later.

Do you need the reading as well as the source?

A plain dry block gives you a temperature. The DBC-A reads the sensor under test on its own reference channels at the same time, which is what a traceable record needs without a second instrument on the bench.

Check insertion depth against your probe

The whole sensing element and a length of stem should sit inside the uniform zone. Depths run from 135 mm to 165 mm, and the aperture pattern in the soaking block is specified when you order.

Electrical rather than temperature?

If you are calibrating transmitters, indicators and loops rather than sensors in a well, the GPS-925 handheld sources and measures the signals directly and is sealed to IP67 for site work.
