PECIFICATION

The Electronic Pressure Transmitter shall have a 1/8 NPT male or female 316 stainless
steel process connection. The Electronic Pressure Transmitter shall measure pressure
to ±0.5% accuracy and output a standard 4-20 mA signal with 100 ohms output
impedance. The Electronic Pressure Transmitter shall be shock and vibration resistant,
overpressure protected, operate within 40-200°F and be NEMA 4 compliant.

RTD RESISTANCE

PROBE THERMOMETER

●304 SS closed end probe measures temperature

● Varies electrical resistance in proportion to temperature

changes

●Communicates change in resistance to automated systems

OPTIONS

●304 SST Thermowell

SPECIFICATION

The RTD shall have a 304 stainless steel closed end probe with a 1/2 inch NPT male
with hex fitting process connection. The RTD shall change resistance in proportion to a
change in temperature and be capable of connecting to a device (such as a signal con­ditioning card) which can convert that resistance change to a standard 4-20 mA signal.
