Product catalog summary
Overview: This document provides technical specifications for various industrial-grade transmitters and switches, including pH/ORP preamplifiers, dissolved oxygen transmitters, pressure transmitters, flow switches, and CO2 transmitters. Each product is detailed with its operational parameters, suitable applications, and key features.
1. pH/ORP Preamplifiers:
  • PHA100: A low-cost preamplifier with bipolar power supply, suitable for pH and ORP measurements in liquids. It operates within 0...60 °C and offers an accuracy of 0.01% of span. It requires a ±5...±8 VDC power supply and has no temperature compensation.
  • PHA150: Features unipolar power supply and temperature compensation, operating from 0...70 °C. It provides an accuracy of 0.05% of span and requires a 5...9 VDC power supply.
2. pH/ORP Transmitter:
  • PHT: Offers low-voltage or mains power supply options, with an operating range of 0...60 °C. It supports pH and ORP measurements with an accuracy of 0.05% of span and includes temperature compensation.
3. Dissolved Oxygen Transmitter:
  • PHO2: Designed for fluids with dissolved O2, operating from 0...55 °C. It provides an accuracy of 1% of span and includes temperature compensation. Compatible with various O2 probes.
4. Pressure Transmitters:
  • PSP: Industrial-grade gauge and absolute pressure transmitter, suitable for non-aggressive fluids. It operates from -40...105 °C with an accuracy of 0.5% or 0.25% of span.
  • PSQ: A low-cost gauge-pressure transmitter for non-aggressive fluids, operating from -40...85 °C with an accuracy of 1...4% of span.
  • PSX PSQA PSF21x: Ex-rated gauge and absolute pressure transmitter, operating from -40...85 °C with an accuracy of 0.5% or 0.25% of span.
5. Flow Switches and Meters:
  • PSF50: Paddle flow switch suitable for low-viscosity liquids, operating from -40...85 °C with an accuracy of 25% of span.
  • PSF20x: Flow meter/transmitter with digital display, suitable for clear and translucent liquids, operating from -10...65 °C with an accuracy of 1% of span.
  • PSF100: Thermal flow switch for low-viscosity liquids, operating from -10...65 °C with an accuracy of 10% of span.
6. CO2 Transmitter:
  • PHG: Designed for air, operating from 0...50 °C with an accuracy of 2 ppm. Suitable for food industry applications with a local display option.
Key Features: The document highlights critical parameters such as operating temperature, protection class, accuracy, power supply requirements, and connectivity options for each product. It also notes specific applications and compatibility with various probes and sensors.
