1.1 Introduction
Field Temperature Blocks (FB150, FB350, and FB660) are designed to be reliable,
stable heat sources that can be used in the eld or laboratory. They offer accuracy,
portability, and speed for nearly every eld calibration application. The instruments
have been designed with the eld user in mind and are easy to use while maintaining
stability, uniformity, and accuracy comparable to some laboratory instruments.
Special built-in features make Field Temperature Blocks extremely adaptable. The
exclusive Voltage Compensation allows the technician to plug into mains power with
voltage from 90 V ac to 250 V ac without degradation to the instrument. The Ambient
Temperature Compensation provides the largest operating range in the industry (0°C
to 50°C) with the largest guaranteed temperature range (13°C to 33°C). The Gradi-
ent Temperature Compensation keeps the axial gradient within specication over the
entire temperature range of the instrument and over the specied guaranteed operat-
ing temperature range. These combined features along with the rugged design, light
weight, and small size make this line of instruments ideal for eld applications.
Unique Patent Pending safety features make these the safest eld heat sources avail-
able. The unique Air Flow Design keeps the probe handle cool protecting delicate
instruments and the user. The Block Temperature Indicator shows the user when the
well temperature is above 50°C letting the user know when it is safe to remove the
insert or move the instrument. The indicator light illuminates when the instrument is
energized and the well is above 50°C. If the instrument is removed from mains power,
the indicator light ashes until the well has cooled to less than 50°C.
The optional “-R” version (“FBXXX-R”) combines the heat source with a built-in
reference.
The Field Temperature Blocks’ controller uses a PRT sensor and thermoelectric mod-
ules or heaters to achieve stable, uniform temperatures throughout the block.
The LCD display continuously shows many useful operating parameters including the
block temperature, the current set-point, block stability, and heating and cooling status.
For the -R version, the reference temperature readings are displayed. The display can
be set to show the information in one of eight different languages; English, Japanese,
Chinese, German, Spanish, French, Russian, and Italian.
The instrument’s rugged design and special features make them ideal for the eld or
the laboratory. With proper use, the instrument provides continued accurate calibration
of temperature sensors and devices. Before use, the user should be familiar with the
warnings, cautions, and operating procedures of the block as described in the User’s
Guide.
