They have an extruded aluminum case and use the best origin components and parts, proven by rigorous tests and specified according to the strictest worldwide norms. One or two pressure inputs; gage or absolute pressure, including vacuum. When in single pressure version, they offer one standard universal input that can be 4-20mA, 0-55mV, 1-5Vdc, 0-10Vdc, thermocouples and RTD; also standard is the 24Vdc power supply for two wire transmitter.

Available for use with air and inert gases or sealed for fluids compatible with 316L stainless steel.
Power supply is universal and can be connected from 90 to 240Vac or dc levels when specified. Flexibility and modularity concepts are clear due to the variety of modules available meeting the widest applications. Up to four alarm modules. One or two analog output of 4-20mA, 1-5Vdc or 0-10Vdc. 
Serial communication.

Inputs
One or two pressure inputs for gage, absolute and vacuum pressures. 
Ranges from 10”H2O to 1000psi gage pressure. Absolute pressure ranges from 15psi to 1000psi. Vacuum ranges up to 1atm. Ranges up to 15psi used with air and inert gases. From 15psi to 250psi one can use air or fluids compatible with 316L stainless steel. Sealed for use with fluids for ranges above 250psi.
Single pressure version offers auxiliar universal input for thermocouple (J, K, T, E, R or S under ITS-90), 0-55mV, RTD under DIN 43760, 4-20mA, 1-5Vdc and 0-10Vdc selected by user.
Input impedance of 250 ohms for mA, 10 M ohms for 5Vdc and 2 M ohms above 5Vdc.

Outputs
4-20mA (750 ohms maximum load), 1-5Vdc or 0-10Vdc analog retransmitter.
