Availability: 2-3 Weeks


Quick Overview

SWT-99 Multi-channel Process Indicator. The SWT-99 Multi-channel Process indicator is designed to measure and display up to 8 RTD inputs. The LCD allows up to 8 channels to be displayed at any one time and also the trend of any channel for the preceeding 12 or 90 seconds. The device is equipped with 2, 4 or 8 RTD inputs and 2 electronic relay outputs.

The SWT-99 indicator is intended for measuring and presentation of RTD values from 8 measuring channels. Each channel can be individually designated (described) with any measuring unit. The LCD graphical display allows for visualization of the values from all 8 channels simultaneously. A significant advantage is the possibility of viewing the trends in each measuring channel as the graphs for the last 12 or about 90 seconds. Each device is equipped with electronic relay outputs that can be used to control external devices. There are icons on the screen signalling the status of the outputs
