HT-P05-T100
Combined pressure & temperature transmitter
Both readings from one tapping point, streamed live over RS-485 with a switching 4–20 mA output and a process controller for automatic cut-off.

The reason customers call us: no other Indian manufacturer ships a digital transmitter that reads pressure and temperature on one instrument, streams both live on RS-485, and cuts off your process automatically. One flameproof body replaces three devices in the loop.
One tapping point, one cable run, two measurements. The HT-P05-T100 replaces a pressure transmitter, a temperature transmitter and a separate process switch with a single flameproof instrument.
The OLED shows both values at the tapping point. RS-485 carries them to your SCADA or PLC in real time. The 4–20 mA output with a NO/NC relay drives a pump, valve or hooter directly, and the process controller trips at a set-point you choose.
What it does
Every unit is assembled and tested in Delhi by Engineers Point.
- Two measurements, one instrumentPressure and temperature from a single process connection — half the tappings, half the wiring, one calibration visit.
- RS-485 live dataBoth values stream continuously to your existing monitors. Log, trend and alarm without an add-on transmitter module or gateway.
- 4–20 mA output with NO/NC relayStandard analogue loop for your DCS, plus a dry relay contact that can switch equipment directly from the transmitter.
- Process controller with auto cut-offSet the cut-off value and the process is switched for you — no separate pressure switch wired into the loop.
- Flameproof, field-ratedEx db IIC T6 Gb die-cast aluminium enclosure, IP65, stainless steel wetted parts for hazardous and washdown areas.
- Tested and documented per unitEvery transmitter ships with its own inspection record sheet: pressure checked at 0, 2.5 and 5 bar on rising and falling stroke, temperature at 0 and 100 °C, certified to ±0.25 % FS with a traceable serial number.

Ordering options
What you can change, and what is fixed.
| Parameter | Standard | Options |
|---|---|---|
| Pressure range | 0–5 bar | Fixed on this model |
| Temperature range | 0–100 °C | Fixed on this model |
| Outputs | RS-485 + 4–20 mA (NO/NC) | Fixed on this model |
| Process connection | ½″ thread | Other threads on request — confirm before ordering |
| Cut-off set-point | Set to your process | Configured at the factory, re-settable on site |
The green model ships in one fixed configuration so the dual-measurement electronics stay calibrated. For custom ranges, probe lengths or thread sizes, the blue HT-P05 and red HT-T100 are built to order.
Every unit is tested before it ships
Each HT-P05-T100 carries its own serial number and inspection record sheet, so the calibration is traceable to the instrument in your hand.
| Check point | Rising stroke | Falling stroke |
|---|---|---|
| 0 bar | 0.000 bar | 0.002 bar |
| 2.5 bar | 2.501 bar | 2.499 bar |
| 5 bar | 4.998 bar | 5.000 bar |
| 0 °C (100.000 Ω) | 0.220 °C | 0.230 °C |
| 100 °C (138.510 Ω) | 99.700 °C | 99.8 °C |
Figures above are from a production inspection record sheet (unit no. 2607H0604, July 2026), reproduced as an example of what ships with each transmitter. Pressure is checked at three points and temperature at two, on both rising and falling stroke, and the unit is certified to ±0.25 % FS before it leaves the factory.

Where it goes to work
- Boilers and steam headers where pressure and temperature are read together
- Chemical and pharmaceutical process lines
- Compressor and chiller skids
- Water and effluent treatment plants
- Oil & gas skids in hazardous areas
- Any loop that currently needs a transmitter plus a separate switch
