I am trying to help a client find a pressure sensor and data logger for measuring pressure inside a pressure cooker like InstantPot during cooking. Max temp expected about 125 deg C (257 deg F) and max pressure about 15-20 psi above ambient. The sensor is easy enough to find, but we want to avoid drilling a hole in the pot, so want to combine the sensor (0-5V or 4-20mA as required) with a datalogger in robust housing and magnetically put it on the inside of the lid of the pressure cooker.
Great if said datalogger had bluetooth or wifi to send data out of the cooker, but ok during cooking, but also ok if we only get that data after the end of the cook when the sensor comes out of the pot.
Does anyone know of a small datalogger than can withstand this high operating temperature (most I've looked at can only take 85-90 deg C), high humidity, medium pressure environment, that can accept a relevant external pressure sensor (or has one built in)?
Building an insulating case, somewhat like some oven loggers do, might be an option, but would prefer to avoid cobbling something together if possible, and just buy something fit for purpose. Budget is a fairly minor concern.
