Supported Applications
The Omega PT-104A is a four-channel, high-resolution temperature data acquisition module designed for use with Pt100 and Pt1000 RTD sensors. Beyond temperature measurement, the series supports resistance measurements in ranges of 0 to 375 Ω and 0 to 10 kΩ, as well as voltage inputs ranging from 0 to 115 mV or 0 to 2.5 V. The module is compatible with 2-wire, 3-wire, and 4-wire RTD sensor configurations, with 4-wire Pt100 sensors recommended for the highest accuracy.
The PT-104A facilitates data collection via Windows Logging Software or a provided Software Development Kit (SDK) containing drivers and example code for C, C++, Excel, and LabView. Up to 20 units of PT-104A modules can be connected simultaneously in various configurations.
Operating Conditions & Performance
The module operates within an ambient temperature range of 0 to 70°C (32 to 158°F). For stated accuracy, the environmental condition is specified as 20 to 30°C (68 to 86°F) with a relative humidity rating of 20 to 90% RH. The device features Class 'A' DIN Platinum Elements per IEC 751.
Performance specifications include:
- Temperature Range: -200 to 800°C (-328 to 1472°F)
- Resolution: 0.001°C for temperature; 1 μΩ and 0.156 μV for resistance/voltage
- Accuracy @ 25°C: 0.01°C (temperature), 20 ppm (resistance), or 0.2% (voltage)
- Linearity: 20 ppm
- RMS Noise (Using Filter): 0.01°C for temperature; 10 ppm for resistance/voltage
- Conversion Time Per Channel: 720 mS
- Input Impedance: >>1 MΩ
- Overvoltage Protection: ±30V
The response time is less than 75 milliseconds in water flowing at 3 feet per second.
Configuration Options
The PT-104A series offers flexible connectivity and power options through USB or Ethernet interfaces. The module can be powered via USB (USB 1.1: 5V ±10% @ <100 mA; USB 2.0: 5V ±10% @ <200 mA) or Power-Over-Ethernet (PoE). It conforms to IEEE 802.3af PoE standards and is compatible with 10/100/1000Base-T networks.
Key configurable features include:
- Sensor Inputs: Supports Pt100 and Pt1000 RTDs in 2, 3, or 4-wire configurations via a 4-pin mini DIN connector
- Data Interface: USB (conforms to USB 2.0 full-speed at 12 Mbps) or Ethernet (IEEE 802.3 10Base-T)
- Software Support: Includes Windows Logging and Player Software for data visualization in spreadsheet or graph formats, plus an SDK
- Physical Dimensions: 36 H x 135 W x 184 mm D (1.42 x 5.31 x 7.24") with a weight of 500 g (1.1 lb)
The standard package includes the PT-104A module, USB cable, Ethernet patch cable, four mating mini DIN screw terminal connectors, quick start guide, Windows software, and a complete operator's manual on CD.
Key Product Differences
The series is identified by model number PT-104A as the 4-channel RTD input data acquisition module. The device supports multiple operational modes including USB-only connections, USB-powered with Ethernet data transmission, and full Power-over-Ethernet configurations.
Accuracy specifications vary based on measurement type: temperature accuracy is quoted at 0.01°C for options marked in the specification table; resistance accuracy is 20 ppm; voltage accuracy is 0.2% (with a note that for the 115 mV range, accuracy may vary by 2%). The temperature coefficient is specified as 5 ppm/°C for standard ranges and 100 ppm/°C for specific conditions.
