4-20mA Pressure Transmitter

4-20mA-pressure-transmitterPressure Transmitter

The 4-20mA Pressure Transmitter is easily integrated into an existing SCADA system, digital display and 3rd party data logger. It will provide a continuous, accurate water level reading for a wide variety of applications.

A two-wire 4-20mA Pressure Transmitter current configuration is used with our pressure transmitter which is the most widely used signal transmission for transducers in industrial environments.

PFAS (Per- and Polyflouroalkyl Substances) are used in products such as repellent/non-stick coatings or fire retardants. These chemicals are not known to break down and proven very persistent in the environment. Their potential to impact human health has prompted legislations of set maximum acceptable PFAS concentration levels in drinking water.

Numerous health studies have shown that certain PFAS may:

  • Interfere with the body’s hormones
  • Affect the immune system
  • Contribute to birth defects and/or learning disabilities in children
  • Increase cholesterol levels
  • Increase cancer risk

Heron Instruments is concerned for the environment and has taken steps to help eliminate PFAS sources to our water system. We are pleased to announce our NEW PFAS FREE ZONE, where we manufacture our dipperLog 64, dipperLog VENTED and 4-20mA Pressure Transmitter with wetted materials not known to contain PFAS.

“It is the Distributor’s and/or User’s responsibility to ensure chemical, temperature, radiative, and shock compatibility with their site(s) before, during and after deployments. Not doing so will void any and all warranties”
