DESCRIPTION:

The Submersible Pressure Transducer - 6640 Series provides high accuracy over a wide range of operating conditions, making it ideally suited to environmental monitoring applications such as surface water, streams, and reservoirs.

The Submersible Pressure Transducers are built in the USA and feature a compensated temperature range of 14° to 178° F (-10° to 80° C), a durable stainless steel housing (titanium optional for severe applications, Model 6642-00), and a dual output (analog & RS-485). RS-485 permits you to calibrate your Submersible Pressure Transducers in the field.

The Submersible Pressure Transducers analog output is programmed at the factory for the desired measurement range. The Submersible Pressure Transducers are programmed via an Interface Converter, Model 6640-15, with a USB to RS-485 output. It is recommended that each technician with responsibility for maintaining sites equipped with a Submersible Pressure Transducer - 6640 Series have a Model 6640-15 in their toolkit. The 6640-15 allows the technician to set zero and span/range settings for the Submersible Pressure Transducer.

An optional Submersible Pressure Transducer pressure calibrator, Model 5528, is also recommended for maintaining your sensors. This is a highly precise digital manometer with an integrated Max/Min function for calibrating and testing submersible pressure transducers.
