PGW2x.100

Description of the device

Wherever the process pressure has to be indicated locally and, at the same time, centralised, web-based remote monitoring is required, this IIoT-capable measuring instrument finds its use. The all welded and robust Bourdon tube measuring system produces a pointer rotation proportional to the pressure. The process pressure is indicated continuously by the pointer on the dial. The measuring electronics convert the pointer rotation into an electronic signal, which is further transmitted via the radio module and the antenna. Battery-operated radio transmission via LoRa® („long range“) is based on LPWAN technology (“low power wide area network”) to enable high transmission ranges and long battery life. The IIoT-capable model PGW2x.100 pressure gauge fulfils safety-related requirements of the relevant standards and regulations for the on-site display of the operating pressure of pressure vessels, as well as the requirements of the Radio Equipment Directive for data communication. In particular, the LoRaWAN® network (“long range wide area network”) enables the complete end-to-end encryption with bidirectional communication for safe IIoT applications. WIKA manufactures and qualifies the pressure gauge in accordance with the requirements of the EN 837-1 European standard in the “S3” safety version. The safety version is made up of a non-splintering window, a solid baffle wall between measuring system and dial and a blow-out back.

PGW23.100.11 Parser Quick Start

Parser API

All functions are pure (no global mutation) except setMeasurementRanges which updates internal range configuration for subsequent decodes.

Types:

Input types:

interface UplinkInput {
  fPort: number // LoRaWAN FPort
  bytes: number[] // Raw payload as array of unsigned bytes (0-255)
  recvTime?: string // Optional ISO timestamp (if your LNS provides it)
}

interface HexUplinkInput {
  fPort: number // LoRaWAN FPort
  bytes: string // Raw payload as hex-encoded string (case-insensitive, even length)
  recvTime?: string // Optional ISO timestamp (if your LNS provides it)
}

Return type (shared by all decode helpers):

type Result = {
  data: Record<string, any> // Parsed key/value pairs
  warnings?: string[] // Non-fatal anomalies
} | {
  errors: string[] // Fatal or structural issues only
}

To understand the data field, take a look at the examples and the schema definition.

Supported channels to identify different sensors by:

// Is used in the returned data
type ChannelName = 'pressure' | 'device temperature' | 'battery voltage'

Channels that support adjusting the measurement range:

type AdjustableChannelName = 'pressure' | 'device temperature'

Channel Configuration

Channel Name	Min Value	Max Value	Unit	Configurable
pressure	0	10	bar / psi / MPa	✓
device temperature	-40	85	°C / °F	✓
battery voltage	0	5	V	-

decodeUplink(input)

function decodeUplink(input: UplinkInput): Result

decodeHexString(hexInput)

function decodeHexString(hexInput: HexUplinkInput): DecodeResult

bytes must have even length; case-insensitive.

setMeasurementRanges(channel, range)

// Will throw on invalid channel name or if the channel disallows range updates
function setMeasurementRanges(
  channelName: AdjustableChannelName,
  range: {
    start: number
    end: number
  }
): void

Applies to future decodes only.

adjustRoundingDecimals(decimals)

// Smartly adjust number of decimals for rounded values
// Impacts all numeric values in all outputs
// Default is 4
function adjustRoundingDecimals(decimals: number): void

Applies to future decodes only.

Verifying Ranges

The pressure and device temperature channels on the PGW23 are configurable. You must verify the actual measurement ranges from your device specifications or identification frames. The battery voltage channel is fixed at 0-5 V. The parser defaults shown in the table above may not match your device configuration.

Using Identification Frames (TULIP2)

This device uses the TULIP2 protocol and sends identification frames (message type 6) containing channel configuration:

{
  "data": {
    "messageType": 6,
    "channelId": 0,
    "channelName": "pressure",
    "measurementRangeStart": 0,
    "measurementRangeEnd": 10
  }
}

Use measurementRangeStart and measurementRangeEnd to configure the parser before decoding data messages.

Quick Start

1. Check your device's actual measurement ranges from purchase configuration, device specifications, or identification frames (see above)
2. Add configuration code below at the bottom of your parser file
3. Add wrapper function if your network server is non-compliant: function decode(input) { return decodeUplink(input) }

Configuration code (add at bottom of parser file):

// Replace values with your device's actual measurement ranges from specifications or identification frames
setMeasurementRanges('pressure', { start: 0, end: 10 })
