General Description

The OMEGA®2-wire SPRTX-SS Series temperature transmitters are high
performance, low cost, industrial transmitters designed for direct connection
to most CIP (clean-in-place) sanitary Pt100 probes and sensors that
incorporate a M12 style connector. All models feature an encapsulated micro
miniature signal conditioner built into a sealed connector housing. The signal
conditioner converts the resistive change of a 100 , 0.00385 RTD probe or
sensor into an industry-standard 2 wire, 4 to 20 mA analog output across a
dedicated temperature range. This analog output can be sent hundreds of feet
away from the location of your sensor (probe) to an indicating device,
controller, PLC, computer, data logger or chart recorder. Your SPRTX-SS
temperature transmitter has been factory calibrated to provide maximum
performance and requires no field adjustments.

Omega’s SPRTX-SS transmitters are available in M12-1 and M12-2 models,
allowing for more flexible international use. The SPRTX-SS1-M12-1 and
SPRTX-SS2-M12-1 are designed for use commonly in North America. The
SPRTX-SS1-M12-2 and SPRTX-SS2-M12-2 are geared towards European
applications.

Introduction/Safety

Your SPRTX-SS Temperature Transmitter has been designed for ease of use
and flexibility. It is important that you read this Users Manual completely
and follow all safety precautions before operating your unit.

Precautions

1. FOLLOW ALL SAFETY PRECAUTIONS AND OPERATING
INSTRUCTIONS OUTLINED IN THIS MANUAL.

2. INSURE PROBE/M12 CONNECTOR CONNECTION IS ALWAYS
FULLY TIGHTENED DURING USE.

3. ADD ADDITIONAL SAFE GUARDS TO YOUR SYSTEM IN
CRITICAL APPLICATIONS WHERE DAMAGE OR INJURY MAY
RESULT FROM PROBE/CONNECTOR SEPARATION OR FAILURE.

4. NEVER EXPOSE THE CONNECTOR/MODULE BODY TO
AMBIENT TEMPERATURES ABOVE 85ºC (185ºF) OR BELOW -40°C
(-40°F). DAMAGE MAY RESULT.

5. DO NOT OPERATE IN FLAMMABLE OR EXPLOSIVE
ENVIRONMENTS.

6. DO NOT USE IN HUMAN MEDICAL OR NUCLEAR
APPLICATIONS.

7. NEVER OPERATE WITH A POWER SOURCE OTHER THAN WHAT
IS SPECIFIED IN THIS MANUAL.

or service your unit will void your warranty.

Theory of Operation

A 4-20 mA loop is a series loop in which a transmitter will vary the current
flow depending on the input to the transmitter. With the SPRTX-SS the
amount of current allowed to flow in the loop will vary depending on the
resistance change, due to changes in the temperature being measured by the
Sanitary RTD sensor (probe). Some advantages of a current output over a
voltage output is that the signal measured is less susceptible to electrical
noise interference and the loop can support more than one measuring
instrument as long as the maximum loop resistance is not exceeded.

A typical application utilizing a current loop will normally consist of a
power supply, the transmitter and a meter, recorder or controller to
measure the current flow. The loop resistance is the sum of the measuring
instruments and wire used. The maximum allowable loop resistance for the
SPRTX-SS to function properly is found by using the following formula:

Rmax = (power supply voltage – 9 volts)/.02 amps

For applications that require a voltage output, the 4-20mA signal from the
SPRTX-SS can be converted in the field by adding a 250 Ohm shunt
resistor that will convert the transmitters output to a 1-5 Vdc signal when
wired correctly.

Protection from High Ambient Temperatures

NOTE:

Your SPRTX-SS Connector/Transmitter Assembly can be damaged if exposed to
ambient temperatures above 85°C (185°F). Some applications may require that
you shield the SPRTX-SS unit from radiated heat as shown below. You should
always use a probe where the length allows for a safe distance of 76 mm (3")
or more between the body of the SPRTX-SS and your source of heat.
