9190A-DW-P-156 Overview

The Fluke 9190A-DW-P-156 Ultra-Cool Field Metrology Well exhibits an extensive temperature range, spanning from -95 to 140 degrees Celsius, with an accuracy of plus-or-minus 0.015 degrees Celsius. This wide range allows it to accommodate the coldest and warmest temperatures needed in pharmaceutical, biomedical, and food processing applications. Unlike traditional calibration baths, the 9190A-DW-P-156 operates at ultra-cold temperatures, which are not typically achievable with bath fluids. Its dry-block design eliminates the need for such fluids, ensuring clean rooms stay pristine and making transportation easier. Additionally, this calibrator provides rapid heating and cooling rates. However, it does not include an insert for accommodating probes.

Besides the 9190A-DW-P-156 Ultra-Cool Field Metrology Well's exceptional temperature stability, its process option denoted as "-P," features 4-20 mA connectors, 24 V dc loop power, a reference thermometer input, and a 4-wire PRT/RTD input. The reference sensor control minimizes the impact of axial gradients when aligning a reference PRT with short sensors. Other process features include:

• Set-point temperature control gets passed from the internal sensor to external reference PRT

• Controls the well temperature based on its measurement and position inside the well

• Automate calibrations of PRTs, thermocouples, and other industrial thermometers

• Accepts common thermocouples with mini-jack termination

• Thermocouple Input Types: J, K, T, E, R, S, M, L, U, N, C

• Smart connector input accepts –A terminated reference PRTs (INFO-CON)

• Reference resistance range 0 to 400 ohm

The –P (process version) Panel of the 9190A

1) PRT Reference Thermometer 6-pin DIN smart connector

2) 4–20 mA connector allows current and/or voltage probes

to be connected for measurement and includes a 24 V loop

power supply when needed to power common transmitters

3) PRT/RTD connector for 4-,3-, and 2- wire measurement

4) Thermocouple connector (subminiature)

5) Fuse for the 4–20 mA circuit

The 9190A Series: Best-in-Class Stability

The Fluke 9190A Series Ultra-Cool Field Metrology Wells are recognized as the market's most precise and steady cold temperature dry-block. They are perfectly suited for tasks requiring rigorous quality control and adherence to regulatory processes. Such tasks encompass on-site verification and calibration of RTDs, thermocouples, thermometers, and sensors that are utilized with process control apparatus like medical freezers, lab refrigerators, cold rooms, blood banks, sterilizers (autoclaves), and freeze dryers.
