Rate or ratio starts drifting
The pulsator may still click, but the delivered pulse no longer matches what the system is supposed to be doing.
Reveal PulseGuard Pro · For dairy parlors running 24 VDC coil-driven pulsators
Closed-loop control for every pulsation point.
PulseGuard Pro drives 24 VDC coil-driven pulsators and verifies what actually happened: rate, ratio, coil current, pulsator output current, vacuum level, and system vacuum for that quadrant.
A setpoint is not proof.
A pulsator can be commanded to run at the right rate and ratio and still behave wrong at the stall. PulseGuard Pro closes that gap by driving the pulsator, measuring the result, and watching the electrical and vacuum conditions around it.
!
Current tells the early story
Coil current and pulsator output current can show abnormal draw, weak coils, shorts, or dropouts before the failure is obvious in the pit.
!
Vacuum changes under load
The box watches vacuum behavior during pulsation and validates system vacuum for that quadrant when the pulsator is idle.
!
Runtime still matters
Once control and monitoring are handled, external triggering and PWM drive reduce unnecessary cycles, heat, power use, and wear.
What PulseGuard Pro actually does.
It is not just a timer and not just a sensor. It controls the pulsator, measures the result, watches current and vacuum, and reports the stall that needs attention.
01
Closed-loop pulsator drive
PulseGuard Pro drives the 24 VDC pulsator coil instead of only watching a legacy output.
02
Actual rate and ratio
Front and rear pressure sensors verify that the delivered pulse matches the target rate and ratio.
03
Current monitoring
Coil current and pulsator output current are watched for weak coils, shorts, abnormal draw, and dropouts.
04
Vacuum level monitoring
The sensors monitor vacuum during pulsation and validate quadrant system vacuum when the pulsator output is not active.
05
Reveal alerts and history
Rate drift, ratio drift, current faults, vacuum faults, and dropouts can be recorded in Reveal so the problem is tied to a specific stall.
06
Lower wear and power
External 24 VDC triggering and PWM coil drive reduce unnecessary runtime, heat, energy use, and pulsator wear.
Control loop
Closed-loop, in plain English.
You tell it what pulsation you want. It drives the pulsator, measures what actually came out, checks the current and vacuum, then corrects or alerts when the stall moves out of line.
1
Drive the pulsator coil
PulseGuard Pro sends the controlled 24 VDC output needed to hit the target rate and ratio.
2
Verify the result
Pressure sensors and current sensing confirm rate, ratio, coil behavior, pulsator output current, and vacuum level.
3
Correct or alert
If the pulse, coil behavior, or quadrant vacuum moves out of line, the operator gets a status and the Reveal system gets the record.
Why one bad pulsator matters to a dairy operator.
A single bad point is not just an equipment nuisance. It can change how a cow milks, how long she stands with a unit on, and what shows up later in the bulk tank.
Teat-end health
Stable b-phase and d-phase timing helps protect the rest phase cows need every cycle.
Fewer slips and squawks
Erratic vacuum events at the teat end are one of the problems you want to catch early.
More complete milk-out
Inconsistent pulse timing can leave residual milk and make takeoff timing harder to trust.
Cow comfort
Cows like rhythm. Bad pulsation can mean fidgeting, stepping, kicking, and slower let-down.
Milk quality risk
Pulsation problems can contribute to teat-end damage, mastitis risk, and problems that eventually show up on the milk check.
Cleaner troubleshooting
When pulsation is known and recorded, every other parlor problem is easier to diagnose.
Less wear on expensive parts
Running pulsators only when a cow is on the unit reduces unnecessary cycles, heat, and service pressure.
Integration
Built for 24 VDC coil-driven pulsators.
PulseGuard Pro is for parlors running standard 24 VDC pulsator coils. One box controls and monitors one pulsation point, using the existing detacher or milk/wash signal to run only when that stall is active.

Install scaleOne per pulsation point
Any major parlor brand
Built for retrofit planning around major systems using standard 24 VDC pulsator coils.
Any parlor size
From a small flat parlor to a large rotary, the model is one watched pulsation point at a time.
Milk/wash trigger input
Connect to the detacher or milk/wash controller so the pulsator output is not cycling between cows.
Lower wear and power
Less unnecessary pulsator runtime and efficient PWM coil drive help reduce energy use and extend pulsator life.
Quadrant vacuum checks
When a stall is not actively pulsing, the sensors still help verify that quadrant has adequate system vacuum under load.
Know which stall needs attention.
PulseGuard Pro gives you a way to catch pulsation and vacuum problems by stall instead of waiting for symptoms in the herd.
