Novatech 1735 Water Vapor Transmitter

Novatech has enhanced its range of analyzers by adding the 1735 water vapor transmitter and the 1231HWV oxygen probe. The 1735 transmitter uses the measure of oxygen to calculate the level of water vapor by using the difference between the wet oxygen reading and the dry oxygen reading.

The Novatech zirconia probes incorporate the world’s most rugged zirconia sensors. Now there is a Novatech oxygen probe designed especially for baking and drying ovens. Used with the 1735 water vapor transmitter, the 1231HWV oxygen probe is capable of reading the oxygen concentration in atmospheres with up to 99.99% water vapor and at temperatures up to 600°C (1,100°F).

Accurate and reliable
The oxygen sensor, which measures water vapor due to oxygen displacement in the oven atmosphere, provides accurate and virtually drift-free measurement for years.

Controlling humidity
The 1735 / 1231HWV can be used with controllers, including PLC’s, to provide accurate continuous control of the moisture level.

Direct fired processes
The 1735 / 1231HWV measures the “wet” oxygen level of the process using an in situ zirconia oxygen probe and can accept a remote signal input (4-20mA) proportional to the dry oxygen level to then calculate the percent water vapor in the process. If this signal is not available from an existing CEMS installation then the 1735 can be supplied with a reference gas sensor (See separate brochure, model 1234) and a simple sampling system to determine the “dry” oxygen level in the process.
