Removable cage cuts cost of sensor replacement

Submersible liquid level/pressure transmitters feature a vented, watertight cable and deliver a high precision 4-20mA solid-state signal while submerged up to 140m.

New from Automation Products Group is the PT-500 series of submersible liquid level/pressure transmitters.

The PT-500 features a vented, watertight cable and delivers a high precision 4-20mA solid-state signal while submerged up to 140m.

A novel (patent pending) removable stainless steel cage connects to the sensor with a simple snap ring and enables users to save significantly on sensor replacement costs.

"The stainless steel cage is a fairly expensive piece of hardware that typically cannot be removed from the sensor, or reused".

"Historically that has meant that each time a sensor needed to be replaced in the field so did the cage at an added cost of $200 or so", says Karl Reid, Engineering Manager.

"Because these types of sensors are used in some nasty environments they tend be replaced on a fairly regular basis, so being able to reuse the cage can deliver exponential savings over a period time", he says.

Rugged IP68 protected PT-500 transmitters are individually tested to deliver accuracy of 0.50% of span, and are temperature compensated to ensure accuracy and long-term stability under extreme temperature variations.

Simple-to-install surface mount technology provides added protection from shock and vibration.

As a result, they are an ideal solution for sewage lift stations, tank liquid level measurement, water and wastewater, well depth measurement and environmental water depth measurement.
