practices for temperature block
calibrators
Ergonomics
• Two-handed carry; built-in
handles on front and back
• All controls and inputs on the
front panel
Stability indicator
• Shows whether block tem-
perature is stable and within
limits defined by the user
PC interface
• USB and RS-232 support
remote operation from a
computer
Dual heater zone
• Active heater zone control
compensates for differential
temperatures between zones
• Minimizes axial temperature
gradients
Ramp-and-soak set-points
• Define up to eight set-point
temperatures; automatically
ramp to and “soak” at each
set-point
• Specify soak time, number of
cycles, and direction
Fast time to temperature and
small footprint
• Compact, efficient free piston
Stirling cooler technology
(FPSC)
Optional process
features
Reference sensor control
• Set-point temperature control
gets passed from the
internal sensor to external
reference PRT
• 9190A controls the well tem-
perature based on its
measurement and position
inside the well
• Helps minimize the effects of
the axial gradient when
reference PRT is aligned with
short sensors
4-20 mA connectors
• Power a 4-20 mA transmitter
from the drywell
• Supplies 24 V dc loop power
4-wire PRT/RTD input
• Reads a 4-wire, 3-wire, or
2-wire PRT/RTD
• Accuracy ± 0.02 °C
• 4-20 mA circuit fuses
Thermocouple input
• Accepts common thermo-
couples with mini-jack
termination
• Types: J, K, T, E, R, S, M, L, U,
N, C
Reference thermometer input
• Smart connector input accepts
–A terminated reference PRTs
• Accuracy ± 0.01 °C at –95 °C
