Setra Corporation Pressure Sensor Terminal Box Model 299 Dry License
The NEMA 4X standard model 299 license from Setra is designed as a terminal box for the field termination of pressure sensors.
The NEMA 4X standard model 299 license from Setra is designed as a terminal box for pressure sensors in the field. The desiccant inside the cover adsorbs moisture from air condensation, providing an effective barrier against moisture intrusion into the sensor part of the pressure transducer. With continuous use, the desiccant changes color from blue (dry) to pink (humidity-saturated), which is indicated through a condition monitoring window. The lifespan of the desiccant is approximately six months, but it can be regenerated by removing the cover and baking it in an oven at about 90°C for 3 to 4 hours. To avoid interrupting system operation, a replacement desiccant cover is provided. The case of model 299 is made of durable fiberglass-reinforced polycarbonate (UL94AB-0) and is designed for easy terminal connections. The NEMA 4X standard for indoor and outdoor installation (IP65) is constructed to include surge protection for the circuit board against voltage surges up to 2000 volts. An optional interface circuit board can convert output signals at a low cost. For pipe mounting installations, a pipe mounting kit is also available.
