The price of a DS18B20 temperature sensor depends on what is being purchased: a component, a finished probe, or a tested assembly with a specified cable and termination. There is no meaningful like-for-like comparison without the same construction, quantity, test requirements, and delivery scope. Request a quote against a drawing and operating conditions rather than relying on an unspecified online price.
Define the product configuration
State whether the requirement is a bare sensing element or a finished digital probe. For an assembly, specify the sheath or encapsulation, probe dimensions, cable length and material, connector, cable exit, strain relief, and any mounting hardware. Changes to these details can change material, assembly, and inspection costs.
Describe environmental and performance requirements
Include the operating temperature span, response need, moisture exposure, immersion or washdown conditions, pressure, chemicals, vibration, and service life. Define any waterproof test method and acceptance criteria for the complete assembly. Additional validation, calibration, documentation, or environmental testing may affect the quote; identify which items are required.
Compare quotes on the same basis
Check that quotes use the same drawing revision, 1-Wire connection, cable/connector, sealing approach, test scope, sample quantity, production volume, packaging, and lead-time assumptions. Confirm whether tooling or special inspection is included and how engineering changes are handled. Compare approved samples before placing a production order if the assembly affects system fit or sealing.
