As a solution provider of measurement and control, RKC is involved in development, sales and other aspects of business. RKC provides: Hardware + Software + Peripheral equipment to satisfy the industry needs. The hardware includes various controllers for temperature, pressure and other processes, power controllers, field network converters, sensors, and custom designed products. The software includes consulting, engineering, before- and after-sales service. Peripheral equipment includes various peripheral equipment necessary to build up a solution. To always provide products of high quality and high reliability, RKC builds and conducts quality management systems at all stages from development, procurement, manufacturing, sales through to shipping and after-sale service.
Inactive gas is supplied to the tube installed in the tank and level is measured using the back-pressure inside the tube that is generated according to the fluid level.
LE110 is a back-pressure type level meter based on LE100 with additional differential pressure (gauge pressure and atmospheric pressure) function. This instrument can be used in a tank where the pressure inside the tank changes.
The use of PFA tube enables measurement of corrosive chemicals.
The range set by the high and the low limits is displayed as 0-100%.
The linearizer function enables level measurement of a vessel with a complicated shape.
This instrument can be also used as a pressure sensor with high repeatability (±0.3% of span).
High Speed Sampling Time 10msec.
Feedback control with 100 samplings per second enables controlling a fast changing process that was difficult to control. Such applications include pressure, flow rate, and pulse heat.
Z-TIO: Temperature control modules : Temperature/Process control modules
Z-DIO: Digital input/output modules: Modules that can handle mode switching and event outputs.
Z-COM: Extended communication module: Module used for data management when a communication conversion module is connected.
Z-CT: CT Input Module: Modules for handling CT inputs for heater break alarm, multiple CT monitoring and overcurrent alarm.
Connection to Ethernet network (MODBUS/TCP, EtherNet/IP, EtherCAT, PROFINET)
We can also provide communication converters that can handle connection to CC-Link, DeviceNet, PROFIBUS, and MECHATROLINK.

Various information is displayed on the large LCD.
At-a-glance monitoring of the controller.
Frequently used keys are assigned to the direct keys. This avoids operator’s operation errors and thus realizes easy-to-understand key operations.
Level-PID function is widely used on Ramp/Soak controllers.
Level setting of each level is automatically calculated by the controller.
Without advanced knowledge, the initial setup will be automatically completed by the controller.
All models are equipped with a front loader communication port for improved maintainability Configuration data management software (PROTEM2) is available
16 segments by 16 pattern The pattern link function allows setting up to 256 segments.
Up to four time signal outputs can be provided in one pattern. The use of logic operation allows setting up to 4 points per DO to handle complicated external sequences.
0.34mm Fiberglass Non-Woven Film or 0.13mm Polyimide（PI）Film are avaible. Ideal for measuring temperature of small objects.
With the dedicated cable with a connector (W-ST-50A), the sensor can be connected to the input terminal of the instrument configured for thermocouple input type K. Wide selections of cable end types are offered. For example, Y-shaped crimp terminal or TC connector.
Since thermal capacity of the sensor itself is very small, temperature can be quickly measured. This makes the sensor suitable for collecting temperature profiles. < ST-50B / ST-51B / ST-51SB characteristic curve>
Bare end type sensors (ST-50B / ST-51B / ST-51SB) are offered for temperature measurement of tiny objects.
The insulated type (ST-51SC) probe prevents the thermocouple wires from contacting the target directly and measures temperature correctly.
*Heat resistant tapes or similar products are recommended while sticking the sensor to the target.
Use of silicon adhesive enables adhesion on almost any objects except some hard-to-bond articles. ※ No Siloxane is generated. Up to 150°C: Capable of repeated use by sticking/removing the sensor. Up to 200°C: Capable of repeated use on condition that the temperature is not lowered below 150°C. Up to 250°C: Capable of repeated use on condition that the temperature is not lowered below 200°C. Above 250°C: Readhesion is not possible. ※The number of repeated use depends on the operating environment
