Keller Series 25Y Flush Diaphragm Temperature Compensated Pressure Transmitter

Quick Overview

The Series 25Y pressure transmitter has digital temperature compensation which provides accuracy of 0.6%FS over 0-50°C or 0.8% over -10 to +80°C. It is available in pressure ranges from vacuum to 600 bar gauge or absolute and can be supplied with 4-20mA, 0-5v, 0-10v or 0.5 - 4.5v outputs. Units are fitted with a fully welded, 316 Stainless Steel, flush diaphragm and a wide range of electrical connection options. Replaces the previous series 25S.

The Y-line transmitters have an extremely small temperature error. This is achieved using an additional circuit containing a temperature sensor that subdivides the temperature range into fields that are 1,5 Kelvin (K) wide. The TK zero and TK compensation values are calculated for each field and programmed into the additional circuit. During operation, these values are fed into the analogue signal path depending on the temperature. Each temperature is the "calibration temperature” for this transmitter.

The Series 25Y product line is outstanding due to its extreme ruggedness towards electromagnetic fields. The limits of the CE standard are undercut by a factor of up to 10 with conducted and radiated fields

The Series 25Y covers pressure ranges of 0.5 to 600 Bar with a fully welded flush diaphragm and can be a vented or sealed gauge at vacuum or atmospheric pressures.
