Temperature

Browse our comprehensive temperature range which covers everything from mechanical temperature switches to wireless temperature transmitters. We manufacture temperature probes and assemblies here in the UK and can build to your specific specification but also hold stock of common sizes and output options.

We have a complete range of thermowells which can be solid drilled or fabricated as well as RTD probes and thermocouples to various specifications. It doesn’t stop there, as there are many different temperature connection heads available as well as temperature transmitters for direct head mounting or remote mounting via din rail. Temperature switches are available as either purely mechanical or electronic with a local display and digital switched output. Our range covers products for use in safe areas to products which are Ex d rated, offering flameproof protection.

Our range of digital thermometers are ideally suited to the process and food industries and come with either plastic or 316 SS terminal heads. Browse our complete range of temperature products below and contact an application engineer today to discuss your requirements.

Temperature measurement technologies we offer

PCT supplies sensors, protection hardware and signal conditioning that integrate cleanly with PLC/SCADA/BMS: wireless telemetry, connection heads, thermowells, probes (Pt100/Thermocouple) and loop/HART temperature transmitters—including ATEX/UKCA variants for hazardous areas. The current line‑up spans Status Instruments in‑head/rail devices, wireless receivers/transmitters, panel indication, and custom probes with both fabricated and solid‑drilled thermowells.

Wireless temperature transmitters & receivers

What they are

Low power radio temperature nodes and receivers/gateways for hard to reach points, mobile assets or retrofit jobs. They cut cabling cost/time and push data to PLC/BMS or local receivers.

Examples we support

WRX900 wireless temperature receiver and WTX700 wireless temperature transmitter within the Status family.

Temperature connection heads

What they are

Field enclosures (e.g., DIN B pattern) that protect the terminal block or in head transmitter. Available in aluminium, stainless, plastic and Ex d / flameproof variants; many accept optional display windows.

When to use

Wherever you need IP rated protection, mechanical strength, or hazardous area compliance adjacent to the sensor.

Thermowells (fabricated & solid drilled)

What they are

Process sleeves that isolate the sensor from pressure, flow and media; enable hot swap probe maintenance; and improve mechanical integrity.

Which type?

  • Fabricated (welded) for general duties and moderate pressures/velocities.
  • Solid drilled (machined from bar) for high pressure, high velocity or vibration; common in steam, utilities and heavy process.

Temperature probes (Pt100 / Thermocouples)

What they are

RTDs (Pt100/Pt1000) for accuracy and stability; Thermocouples (K, J, T, etc.) for high temperatures and fast response (often as mineral insulated inserts).

In our range

PCT supply bespoke probe builds with specified immersion lengths, process threads/flanges, and long leads.

Temperature transmitters (incl. ATEX)

What they are

In head or rail mount devices that linearise and scale RTD/TC inputs to 4–20mA/HART/Modbus; many allow USB/NFC configuration and range setting.

In our range

  • In head: SEM210, SEM310, SEM315 (popular universal inputs). Sales threads show regular quoting/fulfilment, so highlight these SKUs and their configuration flexibility.
  • ATEX/UKCA options: TTR200X temperature transmitter sets with supplied ATEX certification—ideal for Zone 1/2 installs and simple retrofits.

Help me choose (quick guidance from our product range)

  • Harsh duty (pressure/velocity) or high vibration?: Choose solid drilled thermowell + spring loaded insert; use fabricated for general duty to save cost.
  • Hazardous area (Zone 1/2)?: ATEX/UKCA in head transmitter (TTR200X) inside an Ex d or Ex e head.
  • Long cable runs or moving equipment?: WTX/WRX wireless pair; land data in the receiver, then 4–20mA/serial into PLC/BMS.
  • Need universal input & easy range changes?: SEM210/SEM310/SEM315 in head; configure with SpeedLink per your SOP.
  • Panel/bay heat or vibration issues?: Use a rail mount transmitter and keep electronics away from the hot process; head just houses the terminal block.

Frequently asked questions

If you need higher accuracy and stability across typical plant ranges, choose a Pt100/Pt1000 RTD; for very high temperatures or very fast response, pick a thermocouple (K, J, T, etc.). PCT supplies both styles and builds to length with the process connection you need.
  • Fabricated/welded wells are cost effective for general duties at moderate pressures/velocities.
  • Solid drilled wells are machined from bar for high pressure, high velocity or vibration service—our UK deliveries include solid drilled, flanged RTD+thermowell assemblies for heavy process users.
A standard DIN B head protects the terminals or in head transmitter; materials include aluminium, stainless or plastic. For hazardous areas, Ex d (flameproof) heads contain ignition, while Ex e (increased safety) focuses on preventing arcs/sparks—both are common on our range, with windowed options for local indication.
Yes. You stock ATEX rated in head transmitters (e.g., TTR200X) and ship with the required certification pack (evidence of recent CofC + ATEX paperwork). We can also advise on head and gland selection for your zone/gas group.
  • In head keeps the transmitter at the sensor for tidy cabling and simple retrofits.
  • Rail mount puts electronics in a cooler, low vibration panel and leaves only a terminal block in the head—ideal near hot pipework or rotating equipment.
Yes. We routinely pre program Status transmitters (e.g., 0–100°C) and document that configuration; our team also uses a SpeedLink SOP for on site re range and labeling.
Yes. Our catalog includes wireless transmitters and the WRX900 receiver for cable free sensing where wiring is costly or impractical. We’ll match the receiver/gateway option to your control system so the data lands where you need it.
Yes. PCT supplies bespoke Pt100/TC probes with specified immersion lengths, process threads or flanges, long leads and spring loaded inserts—often delivered as a complete RTD + thermowell assembly for hot swap maintenance.
Standard output is 4–20mA for straightforward PLC/BMS integration; selected models support HART for advanced diagnostics/config.
Availability varies by model and build. We have supplied SEM310X ex stock while the SEM310 can run to ≈2 weeks - we will confirm current availability at quote.
