MAMAC Systems TE-213-C-A-2-B-1C2 Temperature Sensor

The MAMAC Systems TE-213-C-A-2-B-1C2 is a high-precision immersion temperature sensor designed for demanding commercial HVAC and building automation systems. This HVAC temperature transducer features a 4-inch stainless steel probe and a 1/2" NPT brass well fitting, ensuring a reliable, pressure-rated interface for chilled water or hot water monitoring. Calibrated at three separate points against NIST-traceable standards, the integrated circuit provides a linear 0-10Vdc output signal over a specific 40-140 degrees F temperature range. The assembly is housed in a rugged, galvanized NEMA-1 steel enclosure, providing protection for the electronic circuit board during field installation. Standard 24Vdc supply voltage powers the unit, which includes non-interacting zero and span trimmers for precise site calibration. The sensor element is protected by a conformal coating to prevent moisture migration, ensuring signal stability and long-term performance in high-humidity mechanical room environments.

• Precision Accuracy: Factory-calibrated sensing element and transmitter assembly verify a +/- 0.5°F full-scale accuracy for critical BAS control loops.
• Industrial Durability: Features a corrosion-resistant stainless steel probe and a sturdy galvanized steel enclosure suitable for mechanical room standards.
• Signal Stability: Output accuracy remains unaffected by long wire runs or electrical noise, facilitating stable 0-10Vdc output integration with controllers.
• Simplified Calibration: Field-adjustable non-interacting zero and span trimmers allow for exact baseline alignment without complex recalibration procedures.
• Moisture Protection: Conformal coating on the 1K Platinum RTD sensor prevents common short-circuit failures caused by condensation or high-delta temperature environments.

Can this sensor be used without a thermowell?
While the unit includes a 1/2" NPT brass fitting for direct mounting, it is specifically designed for use with an immersion well (such as the MAMAC A-500 series) to allow for sensor replacement without draining the hydronic system.

Is the output compatible with 24Vac power supplies?
This specific model (B-1C2) is configured for a 24Vdc supply voltage. Verify your controller output or transformer capabilities to ensure a clean DC power source for the transducer circuit.

How do I calibrate the zero and span settings?
The MAMAC Systems TE-213 arrives factory-calibrated. However, if field adjustments are necessary, use the onboard non-interacting potentiometers to align the 0-10Vdc signal with your reference thermometer at the low and high ends of the 40-140°F range.
