Temperature transmitter

View as Markdown

Head-mounted temperature transmitter on a one-piece flanged thermowell: tapered stem below the raised face, lagging extension, union and nipple, and a dual-compartment Ex d housing with LCD. Origin and port on the flange face (pointing down); insertion and extension lengths are props.

Installation

$npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add temperature-transmitter

Copies instruments/temperature-transmitter.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.

Usage

import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { TemperatureTransmitter } from './components/deck-twin/instruments/temperature-transmitter'

export default function Scene() {
  return (
    <Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
      <Stage>
        <TemperatureTransmitter />
      </Stage>
      <OrbitControls makeDefault />
    </Canvas>
  )
}

P&ID

TT or TIT field bubble joined to a thermowell (a short U-shaped pocket pushed into the pipe, sometimes tagged TW), on the pipe or vessel.

ISA TTISA TITISA TEISA TWISA 5.1 (field-mounted instrument bubble)

TE (element) plus TT (transmitter) of the same loop are one physical item. TI / TG with no transmitter is a dial thermometer (temperature-gauge). A TW bubble on its own is a spare or test thermowell.

For agents

Machine-readable entry with props, ranges, defaults and ports:

$npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info temperature-transmitter

Or fetch /r/temperature-transmitter.json, or copy a ready-made instruction:

Add the Deck Twin "Temperature transmitter" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add temperature-transmitter` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info temperature-transmitter` for its props, ranges and ports. Render <TemperatureTransmitter /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
