Honeywell Analytics Apex Transmitter and Sensor are now obsolete; below are details spares. For a replacement model use the XNX Universal Transmitter, contact us for further help. Previously by Sieger and Zellweger.

The Apex Transmitter was suitable for hazardous area use and included a mounting bracket.  The transmitter had four buttons for configuration/operation and featured a large LCD. Included were three fully configurable relay outputs and selectable sink, source or isolated 4-20mA signal.

Transmitters still in use will accept toxic or flammable gas sensors, smart cartridges are pre-calibrated and configured, allowing instant pairing with the transmitter as it reads the data on install. The sensor can be mounted directly on the transmitter or up to 100m away.
