The Model HVFS Sensor consists of the basic HV sensor housed in a protective plastic enclosure equipped with an air tube connection. This allows aspiration of the sensing element via a vacuum pump with a recommended pumping volume of 1 to 2 SCFH. The aspiration will extend the zone of influence of the sensor for early gas detection in the well and provide considerably faster response time More Info Price

More Info Price

Ronan Engineering’s Model HLS-2 Custom Oil/Water High Level Sensor is designed to monitor fluid levels within oil/water separators. Constructed of stainless steel or brass, PVC, polysulfone, nitrile and beryllium copper, the HLS-2 Sensor will provide years of trouble-free service.

The HLS-2 is installed into the primary tank to provide discrete indications of high oil level and high water levels. Liquid levels sufficient to move the sensor’s float will transmit a signal to the control panel to initiate control functions or annunciate alarms.

Typical applications for the HLS-2 are oil/water separator high level sensing, and high level/overfill monitoring.

FEATURES

• Custom Lengths
• Variety of Materials
• 1/8" NPT to 2" NPT Mounts
• 3-5/8" Flange Mount
• Custom S.G.
• One to Six Discrete Level Points

The HLS-2 is available with a fixed or adjustable mounting for easy periodic testing or future adjustment. The sensor is installed through an available bung at the tank top. The HLS-2 may be supplied with a variety of logic configurations and for a variety of liquid densities. The standard HLS-2 is supplied with N.C. logic for fail-safe operation.

Specifications

• Wetted Parts: Stainless steel or brass; polypropylene, polysulfone, nitrile, beryllium copper, PVC
• Mounting: 1/8" to 2" NPT male or 3-5/8" flange
• Switch Rating: SPST or SPDT, 20VA, 120-240Vac pilot duty
• Operating: -40ºF to +300ºF maximum Temperature: (determined by float material)

More Info Price

The HV Vapor Sensor, a solid state diffusion type, works on the absorption-desorption principle. The detection of a specific vapor is based on the absorption on the catalytic surface at a specific temperature. The gas absorption changes the resistance between the two electrodes embedded in the catalytic element. The resistance change is directly proportional to the vapor concentration and provides the input to the module. The vapor sensor, consisting of the sensing element contained within an anodized aluminum enclosure, is protected by the porous metal-fiber disc which serves as a flame arrestor. The sensor head assembly is UL listed for hazardous locations: Class I, Division 1, Groups B, C and D.
