Ontrol provides some of the best products for measuring pressure. Typical application in HVAC systems are pump and fan speed control, filter condition monitoring, system pressure monitoring for emergency overrides...
The differential pressure transmitters of the 984 series are used to measure differential pressure, overpressure and vacuum. They provide up to 8 pressure ranges and 2 output signals, which are easily selectable by jumper or rotary selector switch.
Adjustable differential pressure switch for monitoring overpressure, vacuum and differential pressure of air or other non-combustible, non-aggressive gases.
Water pressure transmitter VPL 16 is designed to detect pressures at the HVAC automation systems. The pressure is measured with ceramic sensor element. Allowed mediums are water, water/glycol mixtures, air and oils
VPL 16 has four selectable ranges up to 16 bar, and VPL 60 has four selectable ranges up to 60 bar.
VPEL differential pressure transmitter is designed for measuring water/glycol pressures in heating and cooling systems. The transmitters can measure differential pressure and over/under pressures.
Each unit has two measurement ranges, selectable at the time of commissioning.
