	Differential Pressure Indicating Controller	KFDB***	These field mounted indicating controllers have a measuring element for process variables and an indicating controller unit common to all models. By changing the measuring element it is possible to measure and adjust basic process variables for temperature, pressure, flow rate, and liquid level, as well as standard pneumatic pressure signals (20 to 100 kPa). This differential pressure indicating controller (model number KFDB***) converts changes in differential pressure to mechanical changes using a torque arm and torque tube, and indicates and adjusts the flow rate.

	Differential Pressure Indicating Controller	KFPA*, KFKB*	Fixed-range pressure indicating controllers (KFPA*) measure and adjust gauge pressures, pneumatic signals and negative pressures at various ranges by means of spiral or bellows element. Adjustable-range pressure indicating controllers (KFKB*) measure gauge pressures and absolute pressures in various ranges by means of a KF instrumentation unit equipped with a full range of adjustment mechanisms in combination with a detection unit consisting of a highly flexible PREX3000 series pneumatic pressure transmitter.

	Temperature Indicating Controller	KFTA***	The liquid-seal type detection tip of these temperature indicating controllers (KFTA***) detects temperatures from -50 and 300°C in various ranges, and its gas-seal detection tip detects temperatures from 0 to 500°C in various ranges. The instrumentation unit is the KF series, which is equipped with various adjustment mechanisms. A variety of protection tubes is also available.

	Liquid Level Indicating Controller	KFLB***	These liquid level indicating controllers combine a highly accurate and reliable instrumentation unit common to the KF** series with the above mentioned displacement-type liquid-level detection unit to detect and control liquid levels in a variety of ranges from 0–300 mm to 0–3 meters. There are nine available adjustment mechanisms, including on/off, differential gap, and PID operation, enabling selection of the right mechanism for the application.
