USER-FRIENDLY MEASURING DEVICES air handling controller dpt-ctrl Multifunctional PID contoller with differential pressure or air flow transmitter for building automation systems The DPT-Ctrl series PID controllers are engineered for building automation in the HVAC/R industry. With the built-in controller of the DPT-Ctrl it is possible to control the constant pressure or flow of fans, VAV systems or dampers. When controlling air flow, it is possible to select a fan manufacturer or a common measuring probe that has a K-value. DPT-Ctrl series devices include: • PID-controller o Control differential pressure or air flow in duct or across centrifugal fans o All parameters (PID) are adjustable via menu • Differential pressure or air flow transmitter (selectable via menu) o Measure and monitor differential pressure or air flow in duct or across centrifugal fans • Multiple field selectable measurement units: o Volume flow: m3/s, m3/h, cfm, l/s o Velocity: m/s, ft/min o Pressure: Pa, inWC, mmWC, kPa, mbar, psi • Unique proportional output options: o Control output: Voltage (0-10 V) or current (4-20 mA) o Differential pressure or air flow: Voltage (0-10 V) or current (4-20 mA) DPT-Ctrl series device options offer: • AZ (autozero) function for automatic zero point calibration, eliminating the need for periodic manual autozeroing to ensure long term accuracy • AVT series air velocity transmitters • DPT-Flow series air flow transmitters • DPT-R8 series 8-range differential pressure transmitters • DPT-MOD series differential pressure transmitters with Modbus configuration DPT-Ctrl series devices are commonly used in HVAC/R systems for: • Controlling differential pressure or air flow in air handling systems • VAV applications • Controlling parking garage exhaust fans model summary Copyright HK Instruments 2017 www.hkinstruments.fi Datasheet Version 5.0 2017
