Instrotech offers three dual display controllers to industry under the Calog brand.
The Calog DUAL-CTR counter/rate batching controller
This advanced controller features three independent counters with quadrature (x1, x2, x4) and NPN, PNP or TTL sensors which makes it ideal for rate monitoring and batching applications. It has intelligent count modes where users can choose from a variety of smart formulas to suit the application and dual display for simultaneous viewing of multiple variables. Advanced features for this model are batching, batch count modification, programmable input functions, set-point latching and start-up inhibit. Also featured is an intuitive interface with scrolling text prompts and up to four setpoints.
Optional features include the 4-20 mA or 0-10 V analogue output and RS-232/RS-485 serial port.
The Calog DUAL-DEW humidity/temperature controller
Designed for wet and dry bulb, relative humidity applications this unit features dual 4-20 mA analogue output plus dual display for temperature and RH. Other features include dual 3 wire RTD input (385/392, Pt100); dual display or simultaneous viewing of humidity and temperature; intuitive interface with scrolling text prompts. The unit is factory calibrated for 385 RTD – simple recalibration using high and low input signals. Also included are two isolated 4-20 mA analogue outputs for humidity and temperature (up to four set-points) and an RS-232/RS-485 serial port.
The Calog Dual-Flo
An advanced flow batching totaliser and controller which accepts a variety of flow sensor inputs which is compatible with a variety of flow sensors (NPN, PNP, TTL namur, tacho or closed contact). The unit has a single totaliser with flow batching and features easy sensor calibration using direct K factor entry or pulses per unit of measurement. It also has advanced features such as volumetric pulse, latching and start-up inhibit adjustment. Up to 6 set-points are permitted with an optional 4-20 mA or 0-10 V analogue output and an RS-232/RS-485 serial port.
