Description
The Carrier 0843P-0830 is an OEM direct expansion leaving air temperature (DXLAT) sensor designed for use in Carrier HVAC systems. Featuring a 10K Type 2 thermistor element and an 18-inch lead, this sensor delivers precise temperature measurement at the coil leaving-air point — a critical input for accurate system control, capacity management, and freeze protection.
Product Overview
This sensor monitors the temperature of air exiting the DX (direct expansion) coil, providing real-time feedback to the system controller. The 10K Type 2 thermistor is a widely used standard in commercial and residential HVAC controls, ensuring compatibility with Carrier control boards and building automation interfaces that expect this resistance curve.
Key Features
- OEM Carrier replacement sensor — SKU 0843P-0830
- DXLAT (Direct Expansion Leaving Air Temperature) application
- 10K Type 2 thermistor element for accurate resistance-temperature response
- 18-inch lead length for flexible installation positioning
- Designed for integration with Carrier control boards and compatible controllers
- Supports freeze protection, capacity control, and leaving-air temperature monitoring functions
Application
This sensor is intended as a direct OEM replacement for Carrier equipment requiring a DXLAT input. It is commonly used in commercial air handlers, rooftop units, and split systems where leaving-air temperature monitoring is required for proper system operation and protection.
Why Choose OEM?
Using the genuine Carrier 0843P-0830 ensures the correct thermistor curve, lead length, and connector configuration — eliminating guesswork and reducing the risk of control errors caused by mismatched aftermarket sensors.
