Pneumatic Controllers and Transmitters
Powers® Controls 195 Single Input Receiver-Controller
The RC 195 Single Input Receiver-Controller is a pneumatic instrument which receives one
pneumatic input, either direct acting (DA) or reverse acting (RA). It produces a pneumatic
control signal based on the net pneumatic input and the mechanical settings of the setpoint
and percent proportional band.
Part Number: 195-0011

Powers® Controls 195 Multiple Input Receiver-Controller
The Powers® 195 Multiple Input Receiver-Controller is a pneumatic controller that receives
up to three pneumatic inputs and produces a pneumatic output signal based on the net
pneumatic input and the setpoint, percent proportional band, and authority settings. The
controller can be easily changed from direct to reverse acting.
Part Numbers: 195-0001, 195-0003

Powers® 184 Temperature Transmitters
The Powers® 184 Temperature Transmitters are direct acting, one-pipe instruments that
sense temperature and transmit a proportional 3 to 15 psi (21 to 103 kPa) pneumatic
signal to a remotely located receiver gauge and/or receiver controller. Temperature
Transmitters operate on the force-balance principle, using internal feedback for excellent
linearity and accuracy.

HT 186 Humidity Transmitter
The HT 186 Humidity Transmitter is a one-pipe, pneumatic instrument. It senses space
humidity and transmits a proportional 3 to 15 psi (20.7 to 103 kPa) output pressure signal
to a remote receiver gauge calibrated to read percent relative humidity. The transmitter
output may also be sent to a receiver-controller for further control of an air conditioning or
process control system.
