GP275 sensor

Can get ones with integrated controllers. You can take the sensor out of them but it doesn't have the keying on the connector

Haven't played with DeviceNet, RS485, etc direct control on these

Hastings HPM-2002

Interesting but tubes are relatively scarce on surplus market

Nice integrated display + sensor pluggable architecture
