Kayden CLASSIC 810 Thermal Flow, Level & Interface Switch
Kayden CLASSIC 810 Thermal Flow, Level & Interface Switch
Brand: Kayden Instruments
The Kayden CLASSIC 810 Flow, Level, Interface Switch & Transmitter features a precision-welded, highly accurate stainless steel sensor. Alarms and trip points are field-configurable for flow, temperature (high or low), hysteresis, time delay, and more.
Ideal for liquids, gases, and slurries in a clean or dirty process, the CLASSIC 810 is available in a wide range of thread sizes and insertion lengths. Kayden's electronic thermal dispersion flow and level switches have no moving parts to foul, clog, or stick, resulting in exceptional reliability and requiring little to no maintenance.
With no moving parts and minimal invasiveness, Kayden's thermal flow and level switches provide a highly repeatable, accurate, low-cost-of-ownership, long-life, and easy-to-install solution for demanding air, gas, liquid, and slurry applications.
All Kayden® CLASSIC® models feature a rugged flameproof enclosure with blind or glass lens covers. Kayden’s advanced digital electronics will streamline the way you monitor and control your process.
