Request RFQ for Temperature Sensors - Fast Local Supply & Technical Specs

Overview: Requesting an RFQ for temperature sensors

When your project, lab or production line needs temperature sensors in South Africa, submitting a clear request for quotation (RFQ) speeds procurement and reduces lead-time risk. This landing page explains what to include in an RFQ, common sensor types, typical specifications, and how Communica supports local collection, VAT invoicing and account quotes.

What to include in your RFQ

• Project name and intended application (e.g., environmental monitoring, PCB thermal sensing, industrial control).
• Quantity and delivery schedule (single sample, batch of 100, ongoing monthly supply).
• Key specifications: temperature range, accuracy, response time, mounting style, output type (analogue, I2C, 1-Wire, RTD resistance, thermocouple type).
• Environmental requirements: IP rating, vibration, chemical exposure (note: specific claims should reference product datasheets).
• Preferred brands or alternatives (if any) and request for calibration or test certificates if required.

Common sensor types and when to choose them

Quick selection guide: thermistors for low-cost consumer and student projects; semiconductor sensors (e.g., LM35, digital I2C devices) for embedded development; RTDs and thermocouples for industrial/high-temperature ranges. Specify the required interface so suppliers can quote compatible parts and accessories.

Selection criteria, compatibility and accessory guidance

Match sensor electrical interface to your controller. For microcontroller projects, digital I2C or 1-Wire sensors simplify wiring and calibration. For industrial systems, specify industrial temperature sensors for machinery plus the required signal conditioning modules. Indicate required cable lengths, probe mounting (threaded, flange, immersion) and whether you need pre-wired or PCB-mount versions.

Calculations and example: converting thermistor resistance to temperature

A common approach is a voltage divider feeding an ADC and converting resistance via the Steinhart-Hart equation. For quick estimates you can use Ohm's law and the Beta equation for NTC thermistors:

R(T) = R0 * exp(B * (1/T - 1/T0)) where temperatures are in Kelvin, R0 is resistance at T0, and B is the material constant. Use the ADC reading to compute Vout then derive R(T).

Wiring (example for NTC divider to ADC):

Typical procurement and lead-time notes for South Africa

Communica stocks a broad range of sensors from maker favourites and industrial brands; however, lead times for specialised RTDs or calibrated assemblies can vary. When submitting an RFQ, state whether branch collection from Samrand or Pretoria is preferred and whether you need VAT invoices or institutional purchase orders for education or corporate accounts. See our branch locations and trading hours for collection options Branches & Trading Hours.

Quote inclusions and accessory bundles

• Unit price, MOQ, and total price in ZAR (estimate ranges are acceptable when stock is vendor-dependent).
• Estimated lead time, shipping or collection options, and any calibration/test services available.
• Recommended accessories: signal conditioners, probe housings, cable assemblies, connector kits; request bundle pricing when relevant.

Next steps: prepare and submit your RFQ

Prepare a concise RFQ using the checklist above and include contact details and delivery terms. Use the request a quote option on product pages or send your RFQ with specification sheets and quantities; indicate if you require samples for validation. Typical response times vary by item complexity; standard stocked items often receive a same-business-day acknowledgement, while specialised assemblies may need supplier confirmation.
