- For the Model 21 Series Sample Conditioning Package, continuous positive pressure in the process vessel or system provides the force that pushes the sample gas from the process to the sensor. Suitable for applications with process operating pressures between 5 and 300 psig, the Model 21 Series sampler includes a pressure reducing regulator to control the pressure and flow of the sample gas through the system.
- Intrinsically Safe Design — With no moving parts, the pneumatically-powered Model 21 sampler is suitable for hazardous area locations
- Corrosion Resistant NEMA 4X Enclosure — Suitable for indoor or outdoor use with protection against ingress of dust and water
- 316L Pressure Reducing Regulator — Controls the pressure and flow of the sample gas for applications with operating pressures up to 300 psig
- Integral Flow Switch — Opens contacts in alarm when sample gas flow falls below a preset level
- Single or Dual Sensor Compatible — Option for redundant dual sensors enhances reliability
- Internal Vapor Condenser — High efficiency vortex cooler with no moving parts removes contaminants from the sample gas stream
- Low Maintenancece Package — High quality components with few replacement parts minimizes maintenance costs and unplanned downtime
