The Dual Converter Box for Pt100 and Pt1000 Probes on the 1-Wire-UNI Bus
The HW group Converter 2xPt100 1W-UNI connects one or two Pt100 or Pt1000 platinum temperature probes to the 1-Wire-UNI bus. This allows an external Pt100 probe to be used for temperature measurement in virtually any environment. The Converter 2xPt100 1W-UNI can be connected to Poseidon2 or Ares units, enabling the measured values to be transmitted via LAN or GSM.
The Converter 2xPt100 1W-UNI automatically detects Pt100 and Pt1000 probes and allows the external probe to be connected with 2, 3 or 4 wires as required. Typical applications include measuring extreme temperatures in ovens, cooling systems, motors and similar environments.
Since the Converter 2xPt100 1W-UNI features two RJ11 jacks, additional 1-Wire-UNI sensors can be daisy-chained directly, i.e. connected in series, without any extra cabling to the bus master.
High-Precision Temperature Measurement over a Wide Range
The Converter 2xPt100 1W-UNI delivers high accuracy across the entire measuring range with automatic range detection.
Measuring Range -200 to +850 °C
Pt100: -200 °C to +650 °C (±0.3 °C) or up to +850 °C (±0.6 °C), each at +25 °C converter temperature.
Automatic Probe Detection
Pt100 and Pt1000 probes are detected automatically; no manual switching is required.
2-, 3- or 4-Wire Connection
The external probe can be connected with 2, 3 or 4 wires depending on the required accuracy.
Overall System Accuracy
±0.55 °C at 0 °C, ±0.75 °C at 100 °C and ±2.25 °C at 700 °C (each at +25 °C converter temperature, including Pt100/A probe accuracy).
Daisy-Chain Capable
Two RJ11 ports allow further 1-Wire-UNI sensors to be chained.
How the Converter 2xPt100 1W-UNI Is Designed
The compact plastic housing measures 65 x 80 x 30 mm and weighs approximately 200 g (according to the manufacturer’s website 79 x 68 x 30 mm / 114 g – see note at the end of the article).
Plastic Housing with Wall Mounting
The housing is intended for indoor installation and can be mounted using the side lugs.
Two 4-Pole Terminal Blocks
Each of the two probe inputs has its own 4-pole terminal block (contacts 1–4 or 5–8) for connecting the Pt100 or Pt1000 probe with 2, 3 or 4 wires.
Two RJ11 Jacks (1-Wire UNI)
The Converter 2xPt100 1W-UNI is connected to the 1-Wire-UNI bus via the two RJ11 ports; additional sensors can be daisy-chained directly.
Internal Electronics with Auto-Range
The board inside handles automatic detection of Pt100 or Pt1000, range switching and conversion of the measured values into degrees Celsius.
Bus Operation without a Separate Power Supply
The Converter 2xPt100 1W-UNI draws its power directly from the 1-Wire-UNI bus and does not require its own power supply unit.
- Power supply exclusively via the 1-Wire-UNI bus (RJ11)
- One active RJ11 port can supply a maximum of two converters
- To increase power capacity when using more sensors, the manufacturer recommends the “1-Wire hub Power”
- The 1-Wire-UNI bus is not electrically isolated from the temperature probes
- Measuring period: once per second, resolution one decimal place
Integration into Poseidon and Ares Systems
The Converter 2xPt100 1W-UNI can be integrated into existing HW group monitoring systems and counts as two sensors there.
- Compatible with Poseidon 2250, Poseidon 4002, Poseidon2 units and SiteMon5
- Compatible with Ares 12 and Ares 14 for monitoring via GSM/GPRS
- The Converter 2xPt100 1W-UNI counts as two independent sensors in the target device
- Measured values can be transmitted via LAN using SNMP, XML (HTTP) or Modbus/TCP, and via GSM by e-mail or SMS
- Temperature values can be displayed in °C, °K or °F (configurable in the target device)
- Values can also be displayed via the SensDesk.com platform and the associated Android and iOS apps
Eight-Point Calibration for Long-Term Accuracy
The Converter 2xPt100 1W-UNI can be individually calibrated for particularly high measuring accuracy.
- Calibration at up to 8 different points on the measuring curve is possible
- Calibration is performed using a calibration tool for MS Windows and the matching USB calibrator
- Calibration certificates for a specific temperature probe are available at an extra charge
- Optionally, conversion of the input voltage into other units such as mm, hPa, m or ppm can be stored directly in the sensor
