Features

The main requirement of a reference sensor is stability: The less the sensor drifts, the lower the mea-

surement uncertainty. All JOFRA Superior Temperature Reference Sensors are economical and oer fast

—

response times, low immersion depths, compact physical sizes, and specied low drift rates

temperatures. These are all important considerations when selecting a reference sensor.

In addition to the standard straight sensors, we oer a special cable type reference sensor, permitting the

sensor to be positioned throughout the depth of the well in a dry block (for example) under a sanitary

ange. In addition, we have a specic series of intelligent sensors developed for use with the DTI050 refer-

ence indicator.

Quality Dened

It is not easy to make a good quality reference sensor. The main requirement of a reference sensor

is stability. This means minimal drift as a function of operating time at the actual temperature. The

less the sensor drifts, the lower the measurement uncertainty.

Standard Diameter — Fast Response

The STS-100 A/B series has a relatively small diameter: STS-100 A is 4 mm / 0.16 in, and STS-100 B is

6.35 mm / 0.25 in. This leaves optimum space for sensors-under-test in the dry-block, and ensures

a fast response time. A fast reacting sensor will optimize the measurement information.

Reduced Hysteresis and Drift

The sensing element is comprised of a pure plat-

inum coil. This coil is suspended in a way that

minimizes stress and ensures a near zero hysteresis value.

The main reason for drift within a sensor assembly is impurities within the element, especially at

temperatures above 350° C (660° F). All internal parts must be cleaned thoroughly. AMETEK has

developed a unique cleaning method for the internal bore of the Inconel® sheath. The platinum

sensor is embedded within an ultra-clean, temperature resistant ceramic; and assembly of the

components is performed in a clean room. These precautions ensure minimum contamination of

the element during use, and provide the user with the best possible performance.

Aging /Annealing

Once the sensors are assembled, they are subjected

to a long approval process. This includes mechani-

cal stress reduction of the entire assembly as well

as aging the sensor element itself. The purpose of

aging the sensor is to remove the initial drift.

The procedure involves heating the sensor up to 650° C (1202° F) and holding it for 1 hour before

cooling down. This process is repeated over a period of several days. The resistance is then mea-

sured at 0° C (32° F) and recorded. The sensor is again heated up to 650° C (1202° F), and this time

the temperature is held constant for 100 hours.

Time

Finally the output from the sensor is again measured at 0° C (32° F) and recorded. The dier-

ence between the rst and second measurement is recorded. The dierence between these two

measurements is our verication of the stability qualities of the sensor. To be accepted for nal

calibration and certication, the sensor must meet our minimum tolerance, which we document

in a quality certicate.

Reduced Isolation — Resistance-Error

Electrical isolation resistance (parasite-resistance-error) when measured at the highest operat-

ing temperature should be as high as possible. A low isolation resistance would cause the output

signal to be incorrect in relation to the temperature. JOFRA STS-100 A/B series sensors meet the

IEC-751 requirements of isolation resistance by several hundred percent.

The Final Quality-Certificate-Check

Upon completion of every certicate, after nal calibration of the sensor, examination and ap-

proval cycles are performed according to our established procedures. The critical verication is

to ensure that the dierence between the initial and the nal 0° C (32° F) measurement on the

certicate meets our minimum tolerance. These requirements are based on a vast amount of data,

which has been evaluated statistically. This value indicates if the sensor has a sucient long-term

stability. We also check that the linearization coecients have values that correlate to an accept-

able curve sequence in accordance with our requirements.

Certification

The nal documentation on sensors is the calibration certicate. JOFRA sensors have the follow-

ing calibration options.

Accredited Certificate (Standard) Traceable to the European Accreditation Organization.

Temperature range from -45 to 650° C (-49 to 1202° F).

The certicate contains a minimum of 6 temperature points starting and ending at 0° C (32° F).

The certicate also contains calculated linearization coecients.

Delivery Without Certificate — Annealed Only (Optional) In some cases, the customer

may prefer to calibrate the sensor themselves. It is possible to purchase the sensor without any

certication. We do not recommend this option because we are not able to complete the nal

“quality-certicate-check.”

Cable Type

The custom insert and STS-102 A refer-

ence sensor placed in a JOFRA RTC 156

dry-block calibrator. On the right, the

sanitary sensor has been tted into the

insert and is ready for calibration. Note

that the design makes room for the

reference sensor cable.

Specications

For sanitary sensor calibra-

tion, JOFRA has also designed

a special cable type reference

sensor, the STS-102 A. Due

to the small size and exible

connection, the design per-

mits positioning of the sensor

throughout the depth of the

well in a dry-block, eg. under

a sanitary ange.

The reference sensor must be

placed at the same level and in parallel with the sensor-under-test

as indicated in the illustration above. The illustration shows cali

bration of a sanitary sensor. The sensor is in contact with the insert.
