The OMEGA™ 2-wire TX94A-SS
Series temperature transmitters are
transmitters designed for direct
connection to most CIP (clean-inplace)
Sanitary Pt100 probes and
sensors that incorporate a M12 style
connection. All models feature a
miniature signal conditioner built into
a sealed stainless steel connector
housing. The signal conditioner
converts the resistive change of a
100 Ω, 0.00385 RTD probe or
sensor into an industry-standard
2-wire, 4 to 20 mA analog output
across a dedicated temperature
range. Output connection is also a
standard M12 connector.
M12 RTD SENSOR WIRING
Wiring option #1
Wiring option #2
The TX94A-SS transmitter is provided with two RTD wiring configurations as shown. The wiring style is identified at the end of the model number by either a "-1" or "-2". If used with an Omega PR-21 sensor, then the "-1" or "-2" selection should match the final charecters following the "-M12" in the sensor model number (ie: PR-21A-3-100-A-1/4-0600-M12-1). When using the transmitter with an Omega PR-22 style RTD, then please select the -2 wiring configuration. Examples:
For use with a PR-21A-3-100-A-1/4-0600-M12-1, use an TX94A-2-SS-M12F-1 Transmitter (Range is -18 to 93°C).
For use with a PR-22-3-100-A-M6-250-M12 sensor, use an TX94A-2-SS-M12F-2 Transmitter (Range is -18 to 93°C).
SPECIFICATIONS Supply Voltage: 8 to 35 Vdc; (24 Vdc recommended) Max Load: Rmax (Ω) = (Vsupply - 8V)/0.02 A Output: Linearized 4 to 20 mA Accuracy: ±0.1% FS (includes effects of linearity, hysteresis and repeatability) Frequency Response: 3 dB @ 3Hz Range: 1: -40 to 49°C (-40 to 120°F) 2: -18 to 93°C (0 to 200°F) 3: -18 to 149°C (0 to 300°F) 4: -18 to 260°C (0 to 500°F) Input: 3-wire, Pt100 (α = 0.00385), 4-wire RTD compatible Probe/Sensor Input Connection: TX94A-SS-M12M: M12 style, 4-pin male TX94A-SS-M12F: M12 style, 4-pin female Transmitter Operating Temp: -40 to 85°C (-40 to 185°F) Output Connection (All Models): M12 style (order cable from table below) Housing: 316 stainless steel, polished mirror finish Approvals: CE marked Dimensions: 51 H x 38 mm D (2.0 x 1.50")
注: The TX94A-SS series has not been designed for use in medical or nuclear applications, nor flammable or explosive environments. Ordering Example: (1) PSR-24L Power supply, ¥13,890 plus (1) TX94A-2-SS-M12F-2 4 to 20 mA output transmitter with -18 to 93°C (0 to 200°F) temperature range, M12 style 3-pin male connection, ¥25,775, ¥13,890 + 25,775 = ¥39,665
