    • Main features

    The current status is obvious at a glance (Large display + 3-stage display)

    Various information is displayed on the large LCD.

    At-a-glance monitoring of the controller.

    Use of direct keys simplifies the operation

    Frequently used keys are assigned to the direct keys. This avoids operator’s operation errors and thus realizes easy-to-understand key operations.

    The controller adjusts setting according to the equipment to be controlled. (Level-PID automatic setting)

    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.

    Front loader communication port

    All models are equipped with a front loader communication port for improved maintainability Configuration data management software (PROTEM2) is available

    This model can be used in advanced applications that were only handled by upper models

    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.

  • Film Type Temperature Sensors ST-50 series
    Thin Film Type K Thermocouple Temperature Sensor available in thickness of 0.34mm and 0.13mm.<br />Rapid response is best suited for temperature profiling.<br />...

    • Main features

    Film Type Temperature Sensors

    0.34mm Fiberglass Non-Woven Film or 0.13mm Polyimide（PI）Film are avaible. Ideal for measuring temperature of small objects.

    This is a type K thermocouple

    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.

    Excellent response

    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>

    Easy to measure temperature with a cable clamp

    Bare end type sensors (ST-50B / ST-51B / ST-51SB) are offered for temperature measurement of tiny objects.

    Insulated Type

    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.

    Measures max.300°C temperature

    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

  • Back-pressure type level meter LE100 / LE110
    <br />Level measurement and 8 level outputs are possible using one tube.<br />Available with gravity correction function which eliminates correction by actual fluid and EMPTY/SPAN adjustment function which is implemented through one-touch operation.<br />...

    • Level measurement using one tube

    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.

    Easy initial setting (Empty/Span adjustment)

    The range set by the high and the low limits is displayed as 0-100%.

    Can be used as a liquid volume and a pressure meter

    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).
