We are looking for a digital pressure indicator for use with high temperature gas to a maximum temperature of 270 degC, we want to use it occasionally and not in continuous operation, please can you point us to a suitable product?

If the surrounding air temperature is significantly lower below 80 degC we would suggest either the DMK331P which is a sensor for ranges 60 bar and above up to 300 degC, or the DMP331P which is a sensor for ranges 40 bar and below up to 300 degC. Each of these sensors has the option for an integral cooling element which reduces the temperature of any media up to a temperature of 300 degC to a level which is within the designed specification of the electronic and sensing components.
Both of these sensors can be supplied configured with the SRP94 which is a panel mount display indicator, or the PA430 which is a small display readout that mounts directly onto the sensor.
