Pipeline Temperature Sensor NM143 Series

Product Overview

The NM143 series pipeline temperature sensor is a high-precision temperature measurement product independently developed by our company. It is designed with a special structure, which can be directly installed on pipelines or containers for temperature measurement. The product adopts imported high-precision sensitive components, featuring high measurement accuracy, good stability, strong anti-interference ability, and long service life. It is suitable for temperature measurement in various industrial pipelines, heating systems, air conditioning systems, and other occasions.

Product Features

• High precision: Measurement accuracy up to ±0.2℃
• Good stability: Long-term stability ≤0.1℃/year
• Strong anti-interference ability: Effectively resists electromagnetic interference and radio frequency interference
• Easy installation: Can be directly installed on pipelines or containers through threaded connections
• Wide measurement range: -50℃~200℃ (special ranges can be customized)
• Various output signals: Optional 4-20mA, RS485 (Modbus-RTU protocol)
• Durable: Made of high-quality 304 stainless steel material, corrosion-resistant and high-temperature resistant

Product Applications

• Industrial pipelines: Petroleum, chemical, natural gas, water treatment and other industrial pipelines
• Heating systems: Central heating pipelines, floor heating systems, etc.
• Air conditioning systems: Air conditioning water pipelines, air ducts, etc.
• Food and pharmaceutical industry: Production pipelines, storage tanks, etc.
• Environmental protection industry: Sewage treatment pipelines, waste gas treatment equipment, etc.

Technical Parameters

Wiring Diagram

• 4-20mA output wiring (two-wire system):Red wire: Power supply positive (12~24VDC+)

  Blue wire: Signal output / power supply negative (connected to the acquisition device input positive)

  Note: The acquisition device input negative is connected to the power supply negative.

• RS485 output wiring (four-wire system):Red wire: Power supply positive (12~36VDC+)

  Black wire: Power supply negative (12~36VDC-)

  Yellow wire: RS485 A

  Green wire: RS485 B

  Note: It is recommended to use shielded twisted-pair cables for RS485 communication, and the shield layer should be grounded at one end.
