Typical Applications
An Ideal Choice for Challenging Media
Traditional impulse-line transmitters are prone to clogging when handling high-viscosity, crystallizing, or solids-laden media-such as pulp, sludge, crude oil, coatings, or certain chemical solutions.
This product connects directly to the process flange via a flush diaphragm or extended diaphragm, placing a large-area diaphragm in direct contact with the medium; this fundamentally eliminates the risk of clogging and ensures continuous measurement.
A Reliable Solution for High-Temperature and Corrosive Conditions
When measuring high-temperature media (such as liquids exceeding 100°C in reaction vessels) or handling corrosive materials like strong acids and alkalis, the transmitter's electronic components and sensing elements require effective protection.
The design mechanically and thermally isolates the core monocrystalline silicon sensor from the process medium; by selecting appropriate diaphragm materials (such as Hastelloy or Tantalum), the unit can safely and stably withstand these harsh conditions.
A Compliant Choice for Sanitary and High-Purity Applications
Industries such as food, beverage, and pharmaceuticals demand extremely high sanitary standards; equipment must not only use compliant wetted materials but also feature surfaces that are easy to clean to prevent cross-contamination.
With its flush-diaphragm design, this transmitter mounts flush with the inner wall of tanks or pipelines, eliminating dead zones and facilitating easy Cleaning-in-Place (CIP)-making it an ideal configuration for such applications.
Why Choose Our Products?
From an application standpoint, the HNP30-C gets selected for three reasons. First, it solves the plugging problem. On slurries, polymers, or any media that tends to coat or crystallize, the flush diaphragm or extended tube design eliminates impulse lines entirely. No impulse lines means no clogging, no weekly blow-downs, and no unplanned downtime.
Second, the sensor isolation actually works. The piezoresistive element sits at the top of the housing, mechanically and thermally decoupled from the process flange. So when the vessel runs at 110°C, the electronics don't see it. You get real 0.075% accuracy, not a lab number, and the temperature effect stays within ±0.04% URL per 10K. That holds up in outdoor tank farms with 40°C day-night swings.
Third, the interface. The external zero button is dead simple-button, push, done, no opening covers in classified areas. And if you need to tweak range or damping, HART gets you there without dragging a laptop to the top of a tank.
Basically, it's a fit-and-forget device for nasty services. You install it, set it, and check it once a year. That's what operations cares about.
