The ZHEAD-TX can power up any 4-20mA transmitter and transmit the values to a suitable wireless receiver.
Specially designed to maximise battery life the ZHEAD-TX has a range of update rates from 10s up to 1 hour or longer. A typical battery life would be more than 12 months at a 30s update rate. Along with the actual value of the mA transmitter the receiver can indicate the link quality and time since the last received transmission, useful for initiating alarms if a link should be interrupted.
THe ZHEAD-TX is housed in a wall mounting IP65 enclosure and can have either an internal ceramic antenna or an external antenna via an SMA connector.
Any standard 4-20mA transmitter can be connected to the ZHEAD-TX so a complete wireless network can be built up covering all types of process sensors.
