Supported Applications
The ACI Nickel Wall Plate Series is a single-point temperature sensor designed for use with electronic controllers in commercial heating and cooling building management systems. These sensors monitor ambient air temperatures within a space, providing protection and security through their wall-mounted design.
Operating Conditions & Performance
This series operates across an ambient and storage temperature range of -40 to 71°C (-40 to 160°F) with humidity ratings from 10 to 95% RH, non-condensing. The sensor element is a Nickel RTD (PTC) conforming to Din Standard 43760 with a Temperature Coefficient of 6370 ppm/°C over the 0-100°C range.
- Sensor Output: 1000 Ohms nominal at 21.1°C (70°F)
- Response Time: 25 Seconds nominal for a 63% step change
- Self-Heating: 0.3°C/mW in still air; Maximum Operating Current is 5 mA
- Sensor Stability: +/- 0.05% after 1000 Hours @ 150°C (302°F)
Accuracy varies by temperature point as documented:
- -40°C (-40°F): +/- 1.52°C (+/- 2.73°F)
- 0°C (32°F): +/- 0.4°C (+/- 0.72°F)
- 21.1°C (70°F): +/- 0.17°C (+/- 0.34°F)
- 54.4°C (130°F): +/- 0.56°C (1.00°F)
Configuration Options
The series is configured with two non-polarity sensitive, 14" (35.56cm) long leads using 22 AWG (0.65mm) silver-plated copper conductors insulated with Etched Teflon (PTFE). The lead wire rating is MIL-W-16878/4 (Type E), and the wires are color-coded Red/Red.
Housing Materials
- A/1K-NI-SP Series: 430 Stainless Steel with a Brushed Stainless Steel Finish
- A/1K-NI-AP Series: Aluminum with a Smooth Satin Finish, Clear Anodized
Mounting and Accessories
The plates are designed to mount over a standard single gang junction box or directly into drywall using anchors. A foam pad made of Cross-Linked Polyethylene (FMVSS-302 flammability rating) is included to insulate the sensor from thermal drafts within the wall.
- Dimensions: 4.50" (114.3 mm) x 2.78" (70.6 mm) x 0.187" (4.76 mm)
- Tamper Proof Screws (#6-32 x 5/8", Zinc Plated, Flat Head, 1/8") and Tamper-Resistant Screwdriver Insert Bits are available as accessories.
Approvals and Certifications
The series carries CE, RoHS, WEEE, and UKCA approvals. NIST Certificates (3 Points) are available upon request via the custom ordering configuration.
Key Product Differences
Variants within this specific Nickel RTD Wall Plate series differ primarily by housing material and optional certifications:
- A/1K-NI-SP: 430 Stainless Steel wall plate with standard leads.
- A/1K-NI-AP: Aluminum wall plate with standard leads.
- NIST Option: Models can be configured to include a NIST Certificate (e.g., A/1K-NI-SP-NIST).
Other options, including override and communication jacks, may be available upon request but are not detailed in the standard specification sheet.
