Storage Temperature                 -65° to 160°F (-54 to 71°C)

 

Ambient Temperature Limits

 

                    Pressure Models

                             Models 126-164, 610-614: -40 to 160°F (-40 to 71°C);

                             Models 22-28; 16008, 16009: 0 to 160°F (-18 to 71°C)

                    Temperature Models -40 to 160°F (-40 to 71°C). Set point typically shifts less than 1% of range for a 50°F

                            (28°C) ambient temperature change.        

 

 

Shock                                        Set point repeats after 15 G, 10 millisecond duration

 

Vibration                                    Set point repeats after 2.5 G, 5-500 CPS

 

Enclosure Classification          Types C54, C54A, B54, F54, E54, J54, J54A, H54: complies with NEMA 1 requirements.

                                                      Types C54S, B54S, F54S, E54S, J54S, J54AS, H54S: not applicable

 

Set point Repeatability

 

                    Pressure Models

                              Models 22-28, 16008-16009, 126-164: ± 1% of full scale range;

                              Models 610-614: ± 1.5% of full scale range

                     Temperature Models ± 1% of full scale range

 

Switch output                           One or two SPDT snap action switch(es); dual switch may be separated up to 100% of

                                                      range; switches may be wired “normally open” or “normally closed”

 

Electrical rating                       15A 125/250/480 VAC resistive except models 16008-16009 – 20A 480/VAC. Electrical

                                                     switches have limited DC capabilities. Consult UE for additional information.
