ACI A/100-2W-S-4X : Strap-On Temperature Sensor, 100 Ohm Platinum RTD (Two Wires), 1-1/4" to 4" Pipe Size, 14" Etched Teflon Leads, NEMA 4X Enclosure, 5-Year Warranty, Made in USA
The A/100-2W-S-4X is a Platinum RTD (Resistance Temperature Detector) designed for precise temperature measurement in various piping systems. This 2-wire, strap-on sensor is engineered to provide accurate and reliable temperature readings for pipes ranging from 1 ¼” to 4” in diameter.
Key Features:
- High Accuracy: 100 Ohm Platinum RTD with a sensor accuracy of +/- 0.06% at 0ºC, ensuring precise temperature measurements.
- Tough Construction: Encapsulated sensor in a 1.5” square copper plate for improved thermal conductivity between the pipe and the sensor.
- Wide Application: Suitable for cold water systems, hot water systems, retrofit applications, hydronic heating systems, and chillers.
- Wide Operating Range: Can operate in temperatures from -30ºC to 85ºC (-22ºF to 185ºF) and humidity ranges from 10% to 95% RH (non-condensing).
Specifications:
- Sensor Type: Platinum RTD, PTC (Positive Temperature Coefficient)
- Number of Sensing Points: One
- Number of Wires: Two (non-polarity sensitive)
- Sensor Output at 0ºC (32ºF): 100 Ohms nominal
- Response Time: 30 seconds nominal (63% step change)
- Self-Heating: 7 mW/ºC (still air) with a maximum operating current of 5 mA
- Storage Temperature Range: -40ºC to 85ºC (-40ºF to 185ºF)
- Acceptable Pipe Size: 1 ¼” (32mm) to 4” (100mm)
- Lead Length: 14” (35.6cm) with 22 AWG conductor size
- Lead Wire Insulation: Etched Teflon (PTFE) colored leads rated MIL-W-16878/4 (Type E)
- Conductor Material: Silver plated copper
