The connection of sensors is either through plug-in connectors or by integral cables. Different cable types and lengths are available upon request. Plug in connectors are great if the sensor needs to be changed, though integral cables are often more rugged and have better environmental protection.
Cable break monitoring shuts off the flow monitor output if no sensor is connected or if the sensor cable has been severed. In case of cable severing, “flow failure” signal is displayed.
By this we mean that there is no need to connect power, or to connect a telephone line. A wire free telemetry unit is quick and easy to install and less prone to the effects of lightning. The IN4MA METRON provides a cable free installation for applications such as tank level monitoring.
This is the process of checking a measuring system against a standard when the transducer is in a defined environment, and for setting the scaling of an analogue signal to optimise the measurement.
A cell enhancer/repeater provides the same solution as a picocell but without the dedicated capacity benefits. The main difference is that a repeater has an external donor antenna (which may require planning consent). This external antenna is very similar to a standard TV aerial and is used to amplify the existing external signal inside the building.
The term cellular relates to the way that the mobile phone networks are set up. The area is spit into cells at the centre of which is a transmitter/receiver, each cell is set to work on a different frequency from its neighbour to remove interference. Powelectrics use the cellular networks in their GSM / GPRS telemetry solutions.
At the heart of mobile phone is a radio which is often referred to as the cellular engine. GSM telemetry devices use robust and purpose built cellular engines as their means of communication with the outside world.
The current consumption is the maximum current the sensor will draw during operation, without switching load.
