Honeywell 2728 Proportional Pneumatic Controller Direct Acting Dual Sensor

R.A./D.A. PNUEMATIC-ELECTRIC SWITCH R-B ON FALL SP

This Honeywell 2728 Proportional Pneumatic Controller Direct Acting Dual Sensor R-B ON Fall SP is a N.A./A.C. Single Stage Air Compressor, Condenser, Cooler, Chiller and Evaporator. The Dual Sensor Switch has an Excess Flow Plug and a brass bleed valve on the switch body.

The HON 2728 Pneumatic-Electric Controller allows independent control of both a pneumatic and electric actuator from a single controller. It features a fully proportional control, two presets for convenience, and wide operating pressure range from 2 to 35 psig. The HON 2728 is a dual sensor switch with a normally closed (NC) pilot manual reset and a normally open (NO) pilot signal output. This Pneumatic-Electric Controller gives you the ability to simultaneously control two actuators from one valve.''

Honeywell 2728 Proportional Pneumatic Controller Direct Acting Dual Sensor On Fall Stop, On Trip Use With Valve Stem, Mechanical Pressure Switch Use With Solenoid Valve Stem Or Valve Stem, Adjustable Minimum/Maximum Pressure, 0-100 Max PSI Range, Number of Pins 2

This controller with sensor provides the ultimate in proportional motion control. It provides smooth, precise motion with external sensors (up to 36) with no limit switch homing.

The 2728 proportional controller provides a proportional pneumatic output signal based on control inputs from a 28-Vdc to 715-Vdc transformer. The pneumatic controller, in conjunction with a rotor positioner, drive the DC motor in a BLDC motor system to achieve various speeds for a BLDC motor.

The 2728 is a dual sensor pneumatic controller designed to manage direct acting proportional valves. It has all the standard features of the 2727 controller, including set point change, self test, and adjustable hold/reset times.

The 2728 Series Pneumatic Digital Controller provides a proportional, direct acting pneumatic control solution for demanding applications. The 2728 Series comes in a variety of sizes and configurations, and can operate either as single or dual-stage controller. The digital technology of the 2728 Series also enables it to be programmed to three different logic functions: Proportional, Timed Interval and On/Off.

The Honeywell 2728 Proportional Pneumatic Controller, direct acting dual sensor is a controller for use with variable speed drives. The controller can be configured as either proportional or direct acting.

Honeywell's new electronic steam valve controller uses the proven technology of the past with the easy-to-read status of present-day controllers. It is able to be applied to high temperature processes where the application requires proportional control media.

The Honeywell Proportional Pneumatic Controller is for operating electrically fired, liquid fuel boilers. This Pneumatic Control is liquid filled for positive switching, includes an adjustable liquid level indicator, and is direct acting with dual sensors. It includes the power to operate the controllers solenoid valve contacts and an extra easy-to-read dual visual liquid level.

The ultrasonic humidifier uses ultrasonic technology to emit a microfine mist into the air. Humidifying the air, it helps protect sensitive indoor environments by reducing static electricity, absorbing contaminants, and limiting airborne bacteria. The Proportional Humidistat automatically maintains humidity at the optimal level for greater comfort.

The Honeywell 2728 Proportional Pneumatic Controller is a dual-sensor direct-acting pneumatic transmitter that has integral overtravel exhaust, an internal pilot signal output signal for remote piloting or multisensor pressure control, and a linearized output signal for smooth response. It is available in four ranges - 0 to 10 psi, 0 to 5 psi, 0 to 30 psi and 0 to 75 psi. This transmitter delivers proportional outputs of 0 to 100% on both A and B ranges.
