CAUTION

SENSOR/PROCESS APPLICATION COMPATIBILITY

The wetted sensor materials may not be compatible
with process com position and operating conditions.
Application compat ibility is entirely the responsibility
of the user.

INSTALLATION

SENSOR SPECIFICATIONS

The 410VP sensor is available with four process connections: 1½ inch Tri-Clamp1, 2-inch Tri-Clamp, G 1¼, and Varivent N2.
Gaskets and clamps for the Tri-Clamp and Varivent connections must be supplied by the user.

Install the sensor so that the electrodes are completely immersed in the process liquid. Avoid installing the sensor in places
where air bubbles are likely to get trapped or sediment is likely to accumulate on the electrodes. Generally, mounting the
sensor in a vertical pipe run is best. If the sensor must be installed in a horizontal pipe, place the sensor in the 3 o’clock
position. Keep at least 1.0 inch (25 mm) clearance between the end of the sensor and the opposite pipe wall.

To keep response time as fast as possible, do not install the sensor in dead legs or areas where circulation is poor.

WARNING

Before removing the sensor, be absolutely certain
that the process pressure is reduced to 0 psig and
the process temperature is lowered to a safe level!

CAUTION
