Relay
Problem : Many electronic pressure devices come with soft contacts. An additional relay has to be used to drive resistive or capacitive loads. Wiring these up poses a lot of hassles. In most cases only two npn / pnp contacts […]

Problem : Pressure gauges need colour bands to identify the safety or danger bands, for easy communication to the field personnel. For this, the gauge manufacturer has to be indicated in advance about the desired safe and unsafe bands. These […]
Problem : A transmitter has only one output, either current or voltage. The output values are also fixed, eg a 4 – 20 mA transmitter cannot be used for 0 – 20 mA, or 20 – 4 mA output. Same […]
