Now Measure Temperature!
HE CRYSTAL ATMi intrinsically safe temperature modules, with
T
exible cable lengths, oer the functionality and exibility to read
up to 2 temperature inputs with a single HPC50 calibrator. In addition
to the two installed pressure modules in the HPC50 Series, two ATMi
temperature modules can be connected to the device. This provides
the exibility to read pressure with ambient and process temperature in
the same instrument.
The ATMi is engineered to deliver the same high level of accuracy
whether in the lab or in the eld. When combined with the ATMi tem-
perature module, the HPC50 is a powerful calibration tool.
Key Features
Accuracies to 0.015% of Reading.
Performance to meet almost any calibration and measurement task.
Supports Pt100 RTDs.
With readouts in °C, °F, K, R, and Ω.
When
“
combined
with the ATMi
temperature
module, the
Crystal ATMi oers
seamless integration
with the Crystal
HPC50 Series.
Rugged Construction.
–
Machined stainless steel housing. Engineered for rough eld use
almost unbreakable.
Self-Contained, Intelligent Module.
Calibration data is stored in the module, so any module can
be combined with any HPC50 calibrator. No need to “calibrate”
the module to an indicator.

Lab Accuracy in the Field
Active Temperature Compensation
Count on the same accuracy at any temperature, between -20 and 50° C.
Calibrate with Condence Anywhere
Take measurements with up to 0.015% of reading accuracy.
Crystal Engineering calibration facilities are A2LA accredited, (# 2601.01)
which is internationally recognized by ILAC.
Combine with Our Ready To Go Pump Systems
Reference Sensors
The ATMi combines with JOFRA reference sensors to
provide high accuracy temperature measurement on the
HPC50 Series.
An intrinsically safe Pt100 temperature sensor with a spe-
cial non-conductive handle is available with or without
a calibration certicate. Other sensors sizes, temperature
ranges, and accuracies are available from JOFRA
.

Combine the ATMi temperature modules with the HPC50 pressure
calibrator and any of our pump systems for a complete pressure and
temperature calibration system. From small pneumatic hand pumps to a
precision, hydraulic pressure comparator we have the perfect kit for
your application.
Not all sensors ar e in tr insically saf e .

The proper selection of the RTD sensing element is very important as the error associated with this device is the majority of the overall system measurement uncertainty. IEC 751 is the standard that denes the temperature versus resistance for 100Ω, 0.00385 Ω/Ω/°C platinum RTDs. IEC 751 denes two
classes of RTDs: Class A and B. Class A RTDs operate over the -200 to 630°C range versus -200 to 800°C for the Class B elements. For example, the Class A
uncertainty is about half that of the Class B elements as illustrated in the following table.
