Product Overview
The Aplisens LI-24L Rail-Mounted Smart Temperature Transmitter converts RTD, thermocouple, mV, or resistance inputs into a 4–20 mA output with HART and supports dual-channel temperature functions. For accurate selection and pricing, please call 865-900-8844 or email KSmith@CPSCalibrations.com.
The Aplisens LI-24L is a rail-mounted (TS-35) smart temperature transmitter designed to convert RTD resistance or thermocouple voltage (and other supported inputs) into a standard 4–20 mA signal with HART. It includes two separate measuring channels enabling measurement of temperature difference, average, average with redundancy, and max/min temperature. Configuration is performed with a PC + HART/USB converter using Raport 2.
- Output: 4–20 mA + HART
- Inputs: RTD (Pt/Ni/Cu), thermocouples (K, J, S, B, N, T, R, E), mV / resistance ranges
- Cold junction compensation: internal / external (Pt100) / constant temperature
- Diagnostics: autodiagnostic system
- Safety option: SIL2/SIL3 safety version available
- Hazardous area option: intrinsically safe version available
- Mounting: DIN rail TS-35
Need dual-sensor logic (average, redundancy, max/min) or help selecting RTD vs TC? Call us and we’ll match the correct configuration.
