. 1 . DMP305X-TLF Piezoresistive silicon absolute pressure transmitter 2016.04.V1.0 Description Product introduction The new microprocessor and surface mount technology transmission module which collect and process the signal of pressure sensor and amend the measurement error through built-in temperature sensor, fully improved the performance of pressure transmitter. The new external three-button menufunction designs make it easier to operate the parameter settings and safer to operate in dangerous situations.The HART manual controller or the HART software can realize measurement information configuration remotely. Industrial pressure transmitter Main parameters Pressure types Absolute pressure Measuring range 10kPa-3.5MPa, please refer to the ordering information chapter Output signal 4-20mA,4-20mA+HART,customer Reference accuracy 0.2% URL, 0.5% URL Measuring medium Liquid, gas, or steam flow as well as liquid level, density and pressure Field of application Pressure, level Approvals Disclaimer: all the data used in the product description is not legally binding.
