Systems and methods are disclosed for a switched, multiple range sensor system including multiple transducers. In one embodiment, a method is provided that includes receiving and measuring at a first transducer and a second transducer, a pressure to generate a respective first and second pressure signal; amplifying the first and second pressure signals with corresponding first and second fixed-gain amplifier to generate first and second amplified pressure signals; selecting for monitoring, the first or second amplified pressure signal; converting the selected amplified pressure signal to an intermediate digital pressure signal; measuring, at a thermal sensor associated with the selected amplified pressure signal, a temperature; compensating, based on the measured temperature, the intermediate digital pressure signal to generate a compensated digital pressure output signal; and outputting the compensated digital pressure output signal.

A pressure measurement device has: a first chamber coupled to at least one fluid utilization unit, a second chamber coupled to a vacuum source, a seat with a passage for the fluid between the first and the second chamber, a plug for allowing or blocking the fluid flow through the passage, a retaining member for retaining the plug against the seat, a pressure sensor, and a measurement cavity coupled to the first chamber. The retaining member has a channel arranged to couple the first chamber and the measurement cavity.

A self-draining transmitter mount head includes a head body with a transmitter process coupling port in the head body, an impulse port in the head body, and an impulse passage coupled to the impulse port. An impulse drain passage is coupled between the pressure transmitter port and the impulse passage. The impulse drain passage is positioned at an angle to the impulse passage, and relative to a head installation angle that positions the impulse drain passage to drain away from the transmitter process coupling port through a range of head installation angles.

A process variable transmitter manifold is provided that includes a valve body having a valve and a flanged mounting face. The valve body has a port therethrough for selectively coupling a process fluid through the valve, and a cooling channel in the valve body. The cooling channel has an inlet, an outlet, and a passage connecting the inlet and the outlet. A method of controlling temperature of a process fluid in a manifold is also provided. The method includes passing fluid through a channel in the manifold, passing the process fluid through at least one bore through the manifold, and adjusting temperature of the process fluid through conductive cooling or heating of the process fluid based on the certain temperature of the fluid passing through the channel.

A valved tap is disclosed comprising a tap body having a through bore from a threaded input end to an output end thereof. A globe valve is positioned in the valve body so as to interrupt the flow of fluid in the through bore. The output end of the tap body may comprise a flanged portion connectable to a manifold.

An advance pneumatic detector to indicate pressure changes in an environment includes a switch, a pressure tube, an endcap, a piston, and a magnet. The pressure tube is connected to the switch. The endcap is disposed on an end of the pressure tube opposite from the switch. The piston is disposed within and forms a seal against the pressure tube. The piston is slidably engaged with the pressure tube. The magnet is slidably attached to and surrounds a portion of the pressure tube. The magnet is configured to control the positioning of the piston within the pressure tube.

Methods, systems, and devices are provided for controlling fluid flow in a pressure sensing system. A bi-directional valve can include a first capillary that can couple to a process fluid in a process fluid channel, and a second capillary that can couple to a pressure sensor. The first and second capillaries can include an interface therebetween for controlling fluid flow between the first and second capillaries. The interface region can be configured to allow fluid flow between the first and second capillaries when a magnitude of a pressure difference between the first capillary and the second capillary is less than or equal to a threshold pressure. The interface region can also be configured to prevent fluid flow between the first capillary and the second capillary when the magnitude of the pressure difference between the first capillary and the second capillary exceeds than the threshold pressure.

A valved tap is disclosed comprising a tap body having a through bore from a threaded input end to an output end thereof. A ball valve is positioned in the tap body so as to interrupt the flow of fluid in the through bore. The output end of the tap body comprises a flanged portion connectable to a manifold.
