Contrec 120A Level Monitor accepts a 4-20mA signal from a wide range of level sensors, including Pressure Transmitters, Ultrasonic Sensors or Capacitance Probes, and displays
Category: Level Measurement
Level Measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables.
Psychologist Stanley Smith Stevens developed the best-known classification with four levels, or scales, of measurement: nominal, ordinal, interval, and ratio. This framework of distinguishing levels of measurement originated in psychology and is widely criticized by scholars in other disciplines. Other classifications include those by Mosteller and Tukey, and by Chrisman.
The nominal type differentiates between items or subjects based only on their names or (meta-)categories and other qualitative classifications they belong to; thus dichotomous data involves the construction of classifications as well as the classification of items. The Discovery of an exception to a classification can be viewed as progress. Numbers may be used to represent the variables but the numbers do not have numerical value or relationship: for example, a globally unique identifier.
Examples of these classifications include gender, nationality, ethnicity, language, genre, style, biological species, and form. In a university one could also use hall of affiliation as an example.

GPE Instruments Mold Level Measurement
GPE Instruments the Dependable and Cost-Efficient Way to Assure Consistent Surface Quality on Cast Slabs, Blooms, and Billets. GPE assures you of consistent surface quality on your continuous casting by automatically controlling the level of molten metal in your continuous casting operations.
GPE Instruments In manually controlled continuous casting operations, the amount of molten metal entering your mold from the tundish car can continuously shift from too high to too low. This inconsistency can result in surface defects in your cast slabs, blooms, and billets.

Strip Guiding Systems
GPE Instruments in modern process lines contain hundreds of feet of strip moving at high line speeds through narrow roll faces to be wound on enormous coils. Only the most accurate, automatic guiding system can protect such a mill against the product damage and process downtime caused when the strip runs off the rolls. Built for long life under the toughest possible working conditions, they’re backed up by a large service organization. GPE benefits from years of unparalleled strip guide leadership. Their continued top performance is assured by the broadest, deepest knowledge of strip guiding experience anywhere in the world.
- GPE 21550 Heavy Duty Pneumatic Edge Guide Sensor
The Model 21550 Dynaguide Sensor detects edge position pneumatically and transmits this information to a Dynaguide pneumatic-hydraulic controller which uses this information to determine the rate of correction required to maintain the edge at the desired reference position. Recovery pressure is proportional to the material position. - GPE 31560 Photoelectric Textile Sensor
The Model 31560 Edge Guide Sensor is designed primarily for use on pin and clip tenter frames. The sensor detects the edge of the material and transmits an electrical signal to the Dynaguide* Electrohydraulic Controller. The hydraulic controller in turn actuates the hydraulic cylinder positioning the center rail. - GPE 31570 6-Inch Photojet Edge Guide Sensor
The Model 31570 Dynaguide Centerguide Sensor includes two 6-inch Photojet center guide sensors. These sensing heads consist of a light source and photo-conductive cells. The light source is a 6-watt tubular fluorescent lamp that operates on 115 volts AC, 50/60 Hz. - GPE 31551 Heavy Duty Edge Guide Sensor
The Model 31551 Heavy Duty Edge Guide Sensor is specifically designed for heavy-duty strip guiding applications, where maximum versatility is required. The sensor consists of two sturdy cast steel housings that are mounted separately, providing greater installation flexibility. One housing contains the photocell and is available in two options, either photoresistive (cadmium sulfide) or photovoltaic (silicon solar cell). The other housing contains the light source. - GPE 31611 Capacitance Center Sensor
The Model 31611 Capacitance Sensor is designed for intermediate center guide applications where large width variations are encountered and accuracy requirements are not critical. This unique sensor will operate in clouded, dirty, and high-temperature environments, where photoelectric sensors normally cannot be used. It requires little or no maintenance. - GPE 31850 LED Edge Guide Sensor
The Model 31850 LED Edge Guide Sensors are specifically designed for strip guiding applications where maximum versatility is required. The sensor is available in the standard gap (10′ maximum) or wide gap (20′ maximum) housing configurations for any application. Either housing configuration is extremely durable. Both sensors consist of two separate housings that contain the light source and the detector respectively.
