Product Description

The Keli KT28-40P Pressure Switch, part of the KT28 Series Pressure Sensor lineup, is a compact industrial-grade device designed for precise pressure monitoring and control. Featuring 1 analog input (4-20mA) and 1 relay output, it directly interfaces with up to 4 external modules via its built-in RS-485 port supporting Modbus protocol. Operating within 12-24V DC and a temperature range of -20°C to +85°C, it excels in manufacturing, petrochemical, and water treatment applications. This sensor offers ±0.5% F.S accuracy across its 0-40 bar measurement range, with IP65 protection for harsh environments. While lacking wireless capability and onboard display, its rugged housing and DIN-rail mounting simplify installation. Key strengths include reliable overload protection (150% FS) and rapid 10ms response time, though external power is required for operation.
