Description

The model PTM/N/RS485 is a programmable submersible level transmitter, RS485 and analogue output to measure combined pressure and temperature. The model is fully configurable from the data sheet with options on pressure ranges 1 mH2O to 250 mH2O gauge or absolute, RS485 & current 4-20 mA, process connection, cable materials PE, PUR, FEP, PVC, seals and compensated temperature range. Software is provided to allow the adjustment of zero and span. Lightening protection (surge protection) is offered as an optional extra as is the body material with a titanium option. All units are fully tested in the factory for performance and accuracy prior to leaving the factory. Contact us if delivery is of main concern.

The product in question is the Programmable Submersible Level Transmitter PTM/N/RS485, a high-quality sensor designed and manufactured by Strainsense. This device is designed for high flexibility due to its scalable pressure range. It offers both digital (RS485) and analogue (4-20mA) output signals in one sensor and is available as a multi-parameter sensor for pressure and temperature. It is designed for fast customization thanks to its configurable product design.

Key Features:

• The PTM/N/RS485 is available in both stainless steel and titanium versions for use in acidic or otherwise aggressive media.
• It offers lightning protection.
• It is a submersible level transmitter, making it ideal for underwater applications.
