Chapter 1. Product Overview
The Kaye LTR-150 is the next generation, multi-purpose calibrator designed to address the flexibility and
capacity needs for validation calibrations and verifications. As a multi-purpose calibrator, the LTR-150 can
be easily transformed from a standard dry block to a micro bath or surface temperature calibrator, which are
purchasable options. The LTR-150 offers a broad temperature range from -30°C to 150°C with temperature
stability of ±0.01°C and uniformity of ±0.1°C. Performance of calibration and calibration verification can either
be performed automatically via Remote mode or manual through Standard mode.
The Kaye LTR-150 has been designed to interface directly
with all Kaye products (Validator AVS, Validator 2000, IRTD,
ValProbe, and RF ValProbe). The firmware is backward
compatible with all version of Kaye software without need
for software upgrades. This functionality allows the unit to
be utilized for fully automatic calibrations/verifications of
thermocouples, ValProbes or RF ValProbes utilizing your
existing IRTD and applicable Kaye software.
The Kaye LTR-150 also has the flexibility to calibrate other
process or validation sensors in Standalone mode through
the intuitive 7” touchscreen, and a variety of optional inserts.
To maximum accuracy of the control and measurement
during calibration, the LTR-150 includes an external Control
Reference Probe. This probe is used for feedback to the
calibrator controller.
The calibrator is portable, rugged and can be used in a
variety of environments from 0°C to 50°C and humidity ≤80%
(non-condensing).

1.1 Dry-Block Function
The LTR-150 comes standard with a dry block insert containing sixteen (16) wells for thermocouples as
well as two (2) wells for IRTD, and one (1) well for the Control Reference Probe. Each of the sixteen (16)
thermocouple wells is included with a sleeve which can accommodate upwards of three (3) thermocouples.
The sleeves are optimized to handle 22AWG thermocouples, which are similar to the ones currently utilized
in existing Kaye dry block models.

1.2 Micro Bath Function
The LTR-150 has the ability to be utilized as a micro bath for calibration/verification of specialty probes or
even ValProbe Loggers. Utilization of the micro bath functionality requires the purchase of the optional Micro
Bath Kit (PN: 425-3061).
The kit includes a micro bath tub as well as one (1) sensor cage, two (2) magnetic stirrers, one (1) magnetic
lifter, one (1) sleeve exchange tool, one (1) work cover, and one (1) transportation cover. Kaye also offers
Silicon Oil (type 200 -10cs) which can cover the complete temperature range of the calibrator and can be
directly poured into the micro bath tub.
The use of calibration liquids offers certain
advantages if temperatures of unusual shape
and/or size require calibration. The sensor cage
can accommodate up to two (2) ValProbe rigid
loggers. The test item is immersed directly into
the desired liquid medium without an insulating
air gap, resulting in direct temperature contact
between the unit and test item(s). The continuous
adjustment of the magnetic stirrer together with
the removable sensor basket agitates the medium
to create a broad and uniform temperature
measuring zone. Furthermore, the sensor basket
guarantees unhindered stirring, protecting the
tank floor.
The sensor cover reduces evaporation of the liquid to a
minimum and cooling of the liquid surface. The cover is
screwed on to the micro bath and has five (5) openings for
sensors under test.

1.3 Surface Temperature Function
The LTR-150 can also be used for surface temperature calibrations
by utilizing the optional surface temperature insert (PN: 412-3054).
The surface insert is hollow from the bottom and longer than the
adapter sleeve enabling fast and easy calibrations.
The surface temperature insert has a bored hole where the
control reference probe can be inserted which is directly beneath
the contact surface of the insert. This enables very accurate
measurement of the surface temperature. The insert is designed
for optimized homogeneity of the contact surface’s center while
enabling solid thermal contact.
The surface temperature insert is ideal for calibrating / verifying Flat Surface
ValProbes in the temperature range from -25°C to 150°C.
1.4 Calibration Modes
The LTR-150 was designed to offer flexibility and ease of use. To
accommodate these needs Kaye implemented two main modes or menu’s Remote Control mode and
Standalone mode.
Remote Control mode is intended for
Automatic Calibration utilizing Kaye
Validator equipment (Validator 2000,
Validator AVS, ValProbe and RF ValProbe).
In this mode, control of the LTR-150 and
the touchscreen interface is automatically
driven by the appropriate Kaye software.
In the Kaye software, the user configures
the set points, the stability criteria, and
deviation criteria. The user simply starts
the calibration from the Kaye software
and the control of the calibration is
automated. No additional interaction with
the touchscreen is required. The LTR-150
when powered on automatically boots
into the Remote Control screen.
The Standalone mode is intended again
to offer flexibility by allowing fully manual
configuration of the LTR-150 to define all
different kinds of parameters from different
types of sensors, ramp and soaks setups /
profiles to address other calibration needs.
For Standalone mode, refer to Chapter 7.
