ACI A/1K-2W-PM : Small Pipe/Coil Sensor Temperature Sensor, 1K Platinum RTD, 24" Etched Teflon Leads, 5-Year Warranty, Made in USA
The A/1K-2W-PM is a Platinum RTD (Resistance Temperature Detector) pipe mount sensor designed for accurate temperature measurement in various HVAC and process applications. This sensor features a 1.1” brass sensing element with a slight curvature for enhanced thermal conductivity and optimal contact with pipe surfaces.
Key Features:
- Sensor Type: Platinum RTD, PTC (Positive Temperature Coefficient)
- Resistance: 1000 Ohms nominal at 0ºC (32ºF)
- Accuracy: ±0.06% Class A, with a tolerance formula of ±ºC = (0.15ºC + (0.002 * |t|)), where |t| is the absolute temperature in ºC above or below 0ºC
- Operating Temperature Range: -40ºC to 200ºC (-40ºF to 392ºF)
- Storage Temperature Range: -40ºC to 85ºC (-40ºF to 185ºF)
- Humidity Range: 10% to 95% RH, condensing
- Response Time: 8 seconds nominal for 63% step change
- Enclosure Material: Brass
- Pipe Size Compatibility: ½” (12.7mm) to 1” (25.4mm)
- Lead Length: 24” (61cm) 22 AWG (0.65mm) Etched Teflon Colored Leads
- Conductor Material: Silver Plated Copper
- Agency Approvals: CE, RoHS2, WEEE
Applications:
Ideal for use in cooling coils, heating coils, hot water systems, chilled water systems, hydronic heating systems, and chillers. The sensor is suitable for installation on pipes or coils ranging from ½” to 1” in diameter.
Installation:
The A/1K-2W-PM sensor includes a 7.5” nylon wire tie for secure attachment to the pipe. For optimal accuracy, it is recommended to clean the pipe surface, apply thermal grease between the sensor and pipe, and insulate the sensor from ambient air. An optional plenum-rated cable and NIST certification can be ordered for specific needs.
