Introduction
The PLTC-782 portable dry well temperature calibrators are intended to provide an adjustable isothermal environment for
calibration of a variety of temperature sensors and safety switches.
They have been designed under contract for the US Navy.
The isothermal enclosure consists of a fixed thermoelectric or heater block into which removable inserts can be placed.
Temperature sensors requiring calibration are placed in suitably drilled holes in the inserts. A full selection of inserts to
accommodate a variety of sensor diameters is supplied with each PLTC-782.
The main display keeps the operator informed of all pertinent information during the calibration process including; control
set point, well temperature, heating, cooling, or stable condition, thermal switch status, and important user safety
warnings, such as “well touch safe” or “insert too hot to remove”.
A modern interface with unique digital control knob, on-screen alphanumeric keyboard, and traditional membrane keypad
provide new ways to simplify and speed complex operations or data entry.
The PLTC-782 provides users the ability to create, edit, and run, calibration routines to automatically progress through
frequent calibrations of temperature switches or probes. Stored calibration data from the unit under test (UUT) can be
reviewed on the main display or printed directly to a PCL compatible printer via the dedicated USB printer port.
The PLTC-782 has two modes of operation; [Long Stem] which is used for most traditional calibration where the sensor
under test can fit to or near the bottom of the well, and [Short Stem] which changes the calibrator control point to the
midsection of the insert to allow better calibration of short sensors; typically 4” or less.
A unique self-calibration feature allows users to connect an 8.5-digit DMM, such as an Agilent/HP 3458A or Transmille
8104, via the IEEE interface and with a Reference Grade PRT (935-14-95NAV) connected to the DMM the PLTC-782
can run through a 5-point auto Cal/Adjust process. Traditional manual calibration techniques are included as well.
These Temperature Calibrators are available in two models
PLTC – 782: Portable Low Temperature Calibrator covering -40 to 140°C
PHTC – 783: Portable High Temperature Calibrator covering 38 to 660°C
