CONTROL INSTRUMENT

LDS control instruments are a series of single reading controllers that meet a wide range of applications.

LDS has: easy control by encoder wheel, flow control, local & remote control, ERMES web communication, permanent data storage with system log, PT100 temperature probe, stand-by input, alarms, programmable delay at dosing start-up (up to 60 minutes), automatic temperature compensation, probe readout menu (LDSCDIND), different working modes (on/off, impulsive proportional, proportional PWM and fixed PWM), automatic or manual dosing activity and mA output (optional).
