Keller Series 23 & 25 Piezoresistive Pressure Transmitters

Keller Series 23 & 25 Piezoresistive Pressure Transmitters

4+ Weeks Del.

Quick Overview

These piezoresistive pressure transmitter are designed for precision measurements in industrial applications for pressures ranging from 200mBar up to 1,000 Bar for liquids and gases. Series 23 has a standard ¼" BSP threaded connection, whilst series 25 has a ¼" BSP flush diaphragm pressure port. Output options include a 2-wire 4-20mA, 3- wire 0-20mA or 0-10vDC with a standard frequency response of 1kHz with options available for 5kHz and 10kHz.

Details

The series 25 sensors comes fitted with a 1/2" BSP male threaded flush diaphragm pressure port. A flush diaphragms are used in more specialised applications where the media is likely to clog an enclosure process connection, a high level of hygiene is required or an increase in the volume would interfere with the process being monitored. Examples of liquid media would include food or drink, paper pulp, adhesives, paints, pharmaceuticals, medicines, concrete, bitumen, sewage or slurries.
