1. Overview of PendoTECH PressureMAT
The PressureMAT is a monitor, alarm, and transmitter system designed for use with Single Use Pressure Sensors from PendoTECH. It is comprised of the control system box with user interface and the connectors on the back panel where input and output components can be interfaced. If equipped, the alarm output function includes a dry contact relay output. The transmitter function delivers an analog 4 – 20 milliamp output signal corresponding to the pressure reading on the display. There are numerous applications in biopharmaceutical production processes where the system can be used.
The four available models are as follows:

System Components Supplied:
∙Control system
∙Cable(s) for connection of pressure sensors to the control system
∙Connectors for cable for each output
∙4 Screws for mounting hardware
∙Power supply
∙RS-232 cable for data output to a PC (if ordered with the system)
1.1.Control System
The control system with its user interface is used to display pressure readings, zero calibrate the pressure sensor, and to access the program menus to edit the alarm high and low set point values and other tasks.

The process pressure is displayed on the LCD display for each input channel. High and low alarm pressure set points are entered on the keypad for each channel and if the process pressure goes below the low setting or above the high setting, the system will go into alarm state. The alarm function includes activation of the dry contact relay output, a flashing “ALARM>” indication on LCD on the same line as the pressure input channel in the alarm state, and an audible tone for 30 seconds. When an alarm condition goes away, all indicators automatically go back to normal (unless the optional alarm latching function is turned on which requires STOP to be pressure to clear the alarm). The alarm functions are always active for all channels.
1.2.Control System Details
1.2.1.Hardware Details
There is no power switch so the system cannot be accidentally turned off. When the wall power supply is connected to the system and plugged into a wall outlet, the system will turn ON. Instructions to power down the system without unplugging are in Section 1.2.3. The Front and Back Panels details are as shown:
FRONT PANEL:
LCD BACKLIT
DISPLAY
KEYPAD
Note: If a pressure sensor is not connected or is disconnected during operation of the system, the pressure will go to a value greater than 75psi/5.17 bar and an alarm condition will occur. Associated relays will switch and the analog output will send 20mA.
