· Alarm Indications Before It Is Too Late
Refrigeration dryers are among the dryers in compressed air treatment most commonly used. If the required drying is not achieved, the impact of wet air can be serious: Rust in the pipes, failures of machines, and a negative impact on product quality.
The S305 Dew Point Monitor has an optical red backlight which blinks when an alarm is triggered as well as 2 alarm relays which can be used to connect to alarm lights and sirens to warn when dew points are not within the pre-defined ranges. Two alarm levels can be programmed (pre and main alarm).
· Two Measurement Range Models
The S305 can be ordered in two ranges, to perfectly fit your needs:
Option 1: -50… +20 °C Td
Option 2: -20 … +50 °C Td
· Various Connection Options
The connection to the compressed air network is via a 6 mm quick-connector and corresponding connecting hose. The 4 … 20 mA output can be used to connect the dew point monitor to a PLC or a SCADA system.
· Easy Installation and Robust Design
The entire measuring unit is integrated with the display in a rugged housing. The IP65 casing provides robust protection in harsh industrial environments. The dew point monitor is available both as a panel variant or as a wall-mounted housing.
