Your HPC50
Pressure Calibrator

Now Measure Temperature!

HE CRYSTAL ATMi intrinsically safe temperature modules, with

T

exible cable lengths, oer 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 oers

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 Condence 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 certicate. 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 are intrinsically safe.

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 denes the temperature versus resistance for 100Ω, 0.00385 Ω/Ω/°C platinum RTDs. IEC 751 denes 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.
